sim/posix_test: fix shm_open() return file descriptor associated with FD_CLOEXEC
...
Make the pthread_setspecific pass the shm_open/11-1.c testcases. Function shm_open() should return a file descriptor for the shared memory object associated with FD_CLOEXEC. Reference to https://pubs.opengroup.org/onlinepubs/9699919799/functions/shm_open.html and https://github.com/lattera/glibc/blob/master/sysdeps/posix/shm_open.c#LL38C1-L38C1

fs/shm: Add initial implementation for posix shared memory
...
This implements the file system logic for posix shared memory:
shm_open, shm_unlink, mmap, munmap and close
For flat and protected builds the memory simply allocated from (user) heap
For kernel build the memory is allocated from page pool and mapped with MMU
This doesn't yet support protection flags or re-sizing already truncated shared
memory area.
