mesa: fix mismatch when returning 64-bit bindless uniform handles

The slower convert-and-copy process performs a bad conversion
because it converts the value to signed 64-bit integer, but
bindless uniform handles are considered unsigned 64-bit.

This fixes "Check glUniform*() with mixed texture units/handles"
from arb_bindless_texture-uniform piglit.
