d9cfeb0bc3 sched: Don't forward gettid to getpid directly
prepare to implement the right semantics:
getpid should return the main thread id
gettid should return the current thread id

ebdfd16f0f Move gettid() implementation to /libs/libc/unistd
Move sched/task/task/task_gettid.c to libs/libc/unistd/lib_gettid.c.  gettid() is a dumb wrapper around getpid().  It is wasteful of resources to support TWO systme calls, one for getpid() and one for gettid().  Instead, move gettid() in the C library where it calls the single sysgtem call, getpid().  Much cleaner.
