lame: revert "lame: fix CVE-2017-13712"

I don't know how this made it in, but the backported patch most definitely
fails to apply:

ERROR: lame-3.99.5-r1 do_patch: Command Error: 'quilt --quiltrc /home/ak/development/poky/build-musl/tmp/work/core2-64-poky-linux-musl/lame/3.99.5-r1/recipe-sysroot-native/etc/quiltrc push' exited with 0  Output:
Applying patch CVE-2017-13712.patch
patching file libmp3lame/id3tag.c
Hunk #1 succeeded at 195 with fuzz 1 (offset 1 line).
Hunk #11 succeeded at 1023 (offset 24 lines).
Hunk #12 FAILED at 1051.

The reason we have't seen it is that LICENSE_FLAGS_WHITELIST += " commercial"
needs to be in config to trigger this.

This reverts commit fd994b5bede3724ce23f3766e6109d83e534d3f3.
