Subject: [PATCH 04/12] drm/xe: xe_gen_wa_oob: fix
 program_invocation_short_name for macos

From: Daniel Gomez <da.gomez@...sung.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.
