Use getprogname() [1] instead of program_invocation_short_name() [2]
for macOS hosts.

Fixes build error for macOS hosts:

drivers/gpu/drm/xe/xe_gen_wa_oob.c:34:3: error: use of
undeclared identifier 'program_invocation_short_name'    34 |
program_invocation_short_name);       |                 ^ 1 error
generated.

instead of doing that, can we a) include stdlib.h unconditionally and b)
add here a
`static const char *program_invocation_short_name = getprogname()` so we
don't need to change the common case and just handle the "build on
macos" as a compat layer?
