[FFmpeg-cvslog] build: Remove check for gsm/gsm.h for libgsm

[Diego Biurrun]

ffmpeg | branch: master | Diego Biurrun <diego at biurrun.de> | Tue Sep 26 12:13:07 2017 +0200| [8e97a8c69162afce47abea96c8c0914f3550e212] | committer: Diego Biurrun

build: Remove check for gsm/gsm.h for libgsm

libgsm never installed more than a single header, the headers installed into
the gsm/ subdirectory by some distros are private. Who started this nonsense
is a mystery, but it got cargo-culted around ever since.
