gold patch committed: Don't munmap if --keep-files-mapped

This patch to gold avoids calling munmap on a whole file view if
--keep-files-mapped is used.  We will have a whole file view if
--map-whole-files is true, as is the default on a 64-bit host.  When we
want to map the entire file, calling munmap is just a waste of time.
Committed to mainline.

	* fileread.cc (File_read::clear_views): Don't delete the whole
	file view.
