asm-generic/int-ll64.h: always provide __{s,u}64

Several compilers offer "long long" without claiming to support C99.

Considering how frequent __s64/__u64 are used our userspace headers are
anyway unusable without __s64/__u64 available.

Always offer __s64/__u64 to non-gcc non-C99 compilers - if they provide
"long long" that makes the headers compiling and if they don't they are
anyway screwed.
