No change in functionality, just code comprehension

For the SBBS binaries, set @executable_path and
@executable_path/../${LIBODIR} so they can all be in one dir, or
they can be in the build output dirs and still work.

For utilities, set to @executable_path and
@executable_path/../../${LIBODIR} for the same reason.

With this, we shouldn't need to fiddle with DYLD_LIBRARY_PATH

Remove the -E linker flag.
This should not be needed anymore, and isn't supported on macOS.

Have shared libraries include their full path.
This allows linked dylibs to work from where they were built, so
as long as you don't build the binaries on a CI machine, then try
to run them on a users machine (*cough*), it'll work out.

Use the correct rpath argument format on macOS.
It uses -rpath, not --rpath.

Don't return an error if the node#/node.cnf file can't be opened for all uses of load_cfg() except from the terminal server. This fixes #214 for Tracker1

<nelgin> However, dm should probably maintain it at the source.
<nelgin> DigitalMan, I've uploaded gtkuseredit_glade.c which also widens "Sex" to 5 chars
<nelgin> I've also uploaded my .glade file for comparison
<nelgin> and I've uploaded my convert perl script.
<DigitalMan> the sex/gender field is a single character
<nelgin> Yes, but it doesn't display properly unless I widen it to 5.
<DigitalMan> ah

The password was (recently) limited to 8 chars, so that made sense.
The 24 character limit of the real name does not make sense and I can only
assume it was a typo.

Also, fixed get_date(), it returns 0 on success, but the success return logic was inverted:
it only returned 0 if the date was unchanged from the previous value.

Note:
It would be nice if this user editor prompted to save changes if changes have been made a new
user is selected (e.g. with the arrow buttons).

targets.mk:8: *** missing separator (did you mean TAB instead of 8 spaces?).  Stop.

Most of the copyright years in the source code were misleading (the date of
most recent publish was actually later) and all were unnecessary. I've been
removing copyright years piecemeal, for a long time, but I decided it was time
to just perform a bulk search and (mostly) replace. In some cases, I left
old copyright years on files that either are not used (and soon to be removed)
or obsolete and unlikely to ever be touched again (e.g. Win9x FOSSIL VXD). Some
of the runtime binaries still contain copyright years and those were updated to
2018.
