[Toybox] Add -m option to mkdir

[Felix Janda]

Hi,

attached are two patches, one adds the -m option to mkdir (set permissions
of created directory), the other adds a test script for it. The test script
uses the non-standard command stat since it seems to be the right tool for
determining permissions of directories.
