sstate.bbclass: check if mirror directory is writable

Commit 51edde653707e7a3cd2186082458f01f32cd1996 makes a wrong assumption
that SSTATE_MIRRORS have write permissions.

A mirror is by definition outside of it's user control. In my use case
it happens I does not have permissions to update the access time of the
dereferenced symbolic-link file.

Checked if file is writable before changing its atime.

Thanks to Paulo Neves for the patch.
