mod_soundtouch: Use sed to patch configure.ac to use AC_CONFIG_HEADERS

AM_CONFIG_HEADER is deprecated in automake 1.13.1 (and temporarily not available in 1.13),
the replacement is available in autoconf-2.59 (and maybe before).

NOTE: Remove sed hackery when upstream has released a fixed version (> 1.7.0)
