u_format: Use memcpy to avoid unaligned accesses

These functions are used by gl[Get]TexImage, which imposes no
alignment restructions on the void *pixels parameter.

This fixes an unaligned access in GTK's "gtk:gdk / memorytexture" unit
test on SPARC, which causes the test to fail.

Fixes: 45ae4434b5b ("util: Use bitshift arithmetic to unpack pixels.")
