Add some spaces before '('.

This patch fixes various places where a space should have been present
before '(' in accordance with the GNU Coding Standards.  Most but not
all of the fixes in this patch are for calls to sizeof (but it's not
exhaustive regarding such calls that should be fixed).

Tested for x86_64, and with build-many-glibcs.py.
