git-p4: open temporary patch file for write only

The patchRCSKeywords method creates a temporary file in which to store
the patched output data. Previously this file was opened in "w+" mode
(write and read), but the code never reads the contents of the file
while open, so it only needs to be opened in "w" mode (write-only).
