package/libmad: update the patches to be applied with fuzz 0

Commit 8f88a64 ("support/scripts/apply-patches.sh: set the maximum
fuzz factor to 0") reduced the fuzz factor.

Due to this change, libmad fails to build with output:

    Applying mips-gcc4.4.diff using series:
    patching file fixed.h
    Hunk #1 FAILED at 297.
    1 out of 1 hunk FAILED -- saving rejects to file fixed.h.rej

The package applied the patches in two steps, first the local ones and
then the official ones downloaded from the repository. The commit fixes
the issue by reversing the order of patch application steps.
