On FreeBSD, the path argument to shm_open is not a filesystem path and we
must use shm_unlink to remove it. This changes the Linux build to also use
shm_unlink which avoids assuming that shared memory segments live in
/dev/shm.

Currently, subsequent runs of `make localunit` fail and complain about
prior existing /dev/shm/libpod_test and /dev/shm/test1.
This commit deletes these files if existing already, prior to running
the tests.

Renumber is a way of renumbering container locks after the number
of locks available has changed.
For now, renumber only works with containers.

Move SHM specific code into a subpackage. Within the main locks
package, move the manager to be linux-only and add a non-Linux
unsupported build file.
