cmFileLockUnix: Close file descriptor when releasing a lock
The file lock functionality added in commit v3.2.0-rc1~297^2~1 (file:
Add LOCK subcommand to do file and directory locking, 2014-11-26) forgot
to close the lock file descriptors on UNIX. Eventually it was possible
to run out of file descriptors and locks could not longer be acquired.
Fix this by closing the file descriptor when we are done with it.
