From: Daniel Gomez <da.gomez@samsung.com>

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

[1]:
https://www.gnu.org/software/gnulib/manual/html_node/
program_005finvocation_005fshort_005fname.html

[2]:
https://developer.apple.com/library/archive/documentation/System/
Conceptual/ManPages_iPhoneOS/man3/getprogname.3.html

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.

Before adding such #ifdef, you should check how other programs do.

IMO either option is preferred over adding #ifdefs.

This approach looks good to me. I will drop Lucas' tag in favor to this. 
Please, Lucas let me know if you disagree any of the proposals here or 
if you have any preference. Otherwise, I'll resend this with solution 2.
