swr/rast: quit using linux-specific gettid()
Linux-specific gettid() syscall shouldn't be used in portable code.
Fix does assume a 1:1 thread:LWP architecture, but works for our
current target platforms and can be revisited later if needed.
Fixes unresolved symbol in linux scons builds.
v2: add comment in code about the 1:1 assumption.
