Can you (or Igor) share a reason?

'realpath' is not necessarily available. Actually I saw that it may be
not available on Mac OS, but I didn't saw such situation on Linux.
However realpath from busybox does not support -s option (verified on
Alpine 3.10).

My opinion: it is better to don't extend the list of external
dependencies in this case.

I would also highlight that it is quite usual to use just $0 in a usage
message:

 | $ cat --help | head -n 1
 | Usage: cat [OPTION]... [FILE]...

 | $ /bin/cat --help | head -n 1
 | Usage: /bin/cat [OPTION]... [FILE]...
