[PATCH v2 3/8] drm/xe: xe_gen_wa_oob: fix program_invocation_short_name for macos

[Daniel Gomez via B4 Relay]

From: Daniel Gomez <da.gomez@xxxxxxxxxxx>

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

program_005finvocation_005fshort_005fname.html

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.
