[Utils] update_llc_test_checks.py: updated the regexp for ARM target (llvm#148287)

Felle33 · web-flow · commit 54d006180908 · 2025-08-12T15:31:07.000+01:00
Fixes llvm#147485. I changed the regexp for the ARM targets making the part `@+[\t]*@"?(?P=func)"?` optional since when the -asm-verbose=false is passed it is not generated and this led to the issue.
