mesa: Use typecast in BITFIELD64_BIT macro.

Browse source 
Unsigned long is 32bit on several platforms (e.g., Windows), yielding
1UL << 32 to be zero.

Note that BITFIELD64_BIT result is often assigned to variables of type
GLbitfield, instead of GLbitfield64. That's probably wrong and should be
addressed in a later change.
