libcommon: Add syscommon_mkdir()

 It makes directory of the given path, including the whole intermediate
path if not exists. That is, it is equivalent to command 'mkdir -p'.
 It has come from the deviced as the function is eligible to being a
common function to be utilized by overall system libs/daemons.
