Consolidate non cancellable close call
This patch consolidates all the non cancellable close calls to use
the __close_nocancel{_nostatus} identifier. For non cancellable targets
it will be just a macro to call the default respective symbol while on Linux
will be a internal one.
Also, since it is used on libcrypto it is also exported in GLIBC_PRIVATE
namespace.
Checked on x86_64-linux-gnu, x86_64-linux-gnu-x32, and i686-linux-gnu.
