Improve mkdir -Z error reporting.
The most likely reason for setfscreatecon to fail is that you don't have
permission, and that's reported by the write return EACCES. There isn't
really a "bad" context; they're just strings.
Before:
$ adb shell mkdir -Z x y
mkdir: bad -Z 'x'
After:
$ adb shell mkdir -Z x y
mkdir: -Z 'x' failed: Permission denied
Other than this, the ToT mkdir works fine with SELinux.
