http_context: avoid defining our own *buffer_tmpdir methods

Instance variable attr methods are cheaper and we can shove the
complexity down to tmpio by allowing it to accept a nil argument
for the temporary directory.

This adds 4 bytes to tmpio but removes over 1K in http_context
on a 32-bit system.
