package/madplay: fix build when NLS is enabled

MKINSTALLDIRS is not automatically called by autotools when
autoreconfigured.
This leads to the following error during install:

`/bin/sh @MKINSTALLDIRS@ /home/dawncrow/buildroot-test/scripts/instance-0/output/target/usr/share
/bin/sh: 0: Can't open @MKINSTALLDIRS@`

because @MKINSTALLDIRS@ doesn't get substituted during autoreconf.

This particular command only gets invoked when NLS is enabled.

Add patch that explicitly calls AM_MKINSTALLDIRS macro to substitute
every @MKINSTALLDIRS@ occurence in *.in Makefile.

Patch is not sent upstream since upstream is dead.
