  Add __get_errno_ptr() as yet another synonym for __errno_location.

This came up while updating a port for a target that uses this function
name in the implementation of errno.  Tested on that target, and on
x86_64-linux-gnu and aarch64-linux-gnu natives.  Ok to install?

for  gcc/analyzer/ChangeLog

	* kf.cc (register_known_functions): Add __get_errno_ptr.
