v2 cover add CMA test

changes in v2
- dropped configure check as glibc wrapper calls syscall directly, and using syscall(2) we can test also when glibc wrappers are missing
- added simplified process_vm.h

CMA (cross memory attach) feature introduced 2 new syscalls:
process_vm_readv
process_vm_writev

Cross Memory Attach

"The basic idea behind cross memory attach is to allow MPI programs doing intra-node communication to do a single copy of the message rather than a double copy of the message via shared memory." [1]

This patch series is introducing the initial structure under syscalls/cma and first test to check various errno codes as described in proposed man page [2].
