fs: add cdev_create_loop and cdev_remove_loop for loop mount option
Allow to create a loopback cdev from a file.

Fixed up with:
fs: Makefile: Add parseopt to all builds
parseopt.h was included to fs.c with commit 9248b, but parseopt.o has a
dependency to CONFIG_FS_NFS.
Moved parseopt.o to the default build to eliminate build failures.
