git p4: disable read-only attribute before deleting

Browse Source 
On windows, p4 marks un-edited files as read-only.  Not only are
they read-only, but also they cannot be deleted.  Remove the
read-only attribute before deleting in both the copy and rename
cases.

This also happens in the RCS cleanup code, where a file is marked
to be deleted, but must first be edited to remove adjust the
keyword lines.  Make sure it is editable before patching.
