testbot/PatchUtils: Run make_specfiles when a spec file is modified.

Since wine commit wine/wine@401288a7 (make_specfiles: Generate a list of syscalls from the corresponding spec files., 2023-11-16), spec files are used to auto-generate the following files:

• dlls/ntdll/ntsyscalls.h (from dlls/ntdll/ntdll.spec)
• dlls/win32u/win32syscalls.h (from dlls/win32u/win32u.spec)
