This change deprecates CONFIG_POSIX_MQUEUE in favour of
CONFIG_POSIX_MESSAGE_PASSING, which maps directly to the name of the
standard POSIX Option.

Previously, the POSIX shell utilities were intermixed with the
POSIX API implementation.
The POSIX shell utilities only depend on the public POSIX API,
so it makes sense to keep them in a separate subdirectory.
