Fixed last remaining license issues

Three files in libtirpc have the "BSD with advertising" or "BSD 4
clause" license on them (Free, but GPL incompatible). Thankfully, two of
the three files (tirpc/libc_private.h and tirpc/nss_tls.h) aren't
necessary on Linux at all. They were copied from FreeBSD, but FreeBSD
(and NetBSD) include those headers, so they can be conditionalized out
in the code. The third header, tirpc/reentrant.h originally came from
FreeBSD, but had been modified to point to the Linux pthread equivalent
functions. I'm pretty sure that would cause the code to break on
FreeBSD/NetBSD.

This patch does the following:

- Zeros out tirpc/libc_private.h (This file should be deleted from the
  source control)
- Zeros out tirpc/nss_tls.h (This file should be deleted from the source
  control)
- Takes a fresh copy of tirpc/reentrant.h from FreeBSD CVS to inherit
  the new license (the advertising clause has been dropped in FreeBSD)
- Updates tirpc/reentrant.h so that it contains the correct definition
  mappings for Linux, conditionalized only for Linux.
- Updates all source files which #include libc_private.h so that the
  include is conditionalized on FreeBSD or NetBSD. I honestly don't think
  these files even need to be included on those platforms, but I'd rather
  be safe than sorry here.
