nptl: Remove send from libpthread

Browse Source 
The libc version is identical and built with same flags.  Both aarch64
and nios2 also requires to export __send and tt was done previously with
the HAVE_INTERNAL_SEND_SYMBOL (which forced the symbol creation).

All __send callers are internal to libc and the original issue that
required the symbol export was due a missing libc_hidden_def.  So
a compat symbol is added for __send and the libc_hidden_def is
defined regardless.

Checked on x86_64-linux-gnu and i686-linux-gnu.
