prov/opx: Use getpid() instead of gettid() for POSIX compliancy.

belynam · j-xiong · commit 7660f36eccac · 2025-10-09T13:48:58.000-07:00
The 'gettid()' function is not POSIX compliant, and older versions
of glibc may not have that function available in unistd.h, causing
a compile failure. This changes the call to 'getpid()', which is
POSIX compliant and should always be present in glibc.
