Consolidate pthreadtype.h placementConsolidate pthreadtype.h placement

This patch moves all arch specific pthreadtypes.h to a similar path
for all architectures (sysdeps/unix/sysv/<arch>/bits).  No functional
or build change is expected.  The idea is mainly to organize the
header placement for all architectures.

Checked with a build for all major ABI (aarch64-linux-gnu, alpha-linux-gnu,
arm-linux-gnueabi, i386-linux-gnu, ia64-linux-gnu,
m68k-linux-gnu, microblaze-linux-gnu [1], mips{64}-linux-gnu, nios2-linux-gnu,
powerpc{64le}-linux-gnu, s390{x}-linux-gnu, sparc{64}-linux-gnu,
tile{pro,gx}-linux-gnu, and x86_64-linux-gnu).
