Subject: [PATCH] media-libs/mesa: add USE flags to control sha1 dep #539266

The sha1 usage in mesa is a bit convoluted and can leverage a number of
sublibs to satisfy things.  Add USE flags to control them directly.  This
covers the common cases but can probably be further refined.  We'll look
more into it via the bug.
