[committed] OpenMP: Add interop routines to omp_runtime_api_procname

[Tobias Burnus]

I realized that the attached change (committed asr15-3582-g6291f25631500c) was missing from what I committed in 
r15-3249-g0beac1db38855e  libgomp: Add interop types and routines to 
OpenMP's headers and module I also checked the last 5 or so commits to 
omp.h.in, but for those routines, we seemed to have remembered to update 
the API routine check for those. Tobias
