mesa: fix 64-bit issues with system_values_read

We're about to bump the number of system values above 32. The
system_values_read bitfield itself is 64 bits, but some users weren't
taking that into account. Fix the ones I could find by grepping for
"system_values_read". This prevents regressions at least with radeonsi
and other Gallium drivers, and probably i965 too.
