Ganesh Ajjanagadde b4cb597900 libswscale/swscale: fix -Wunused-function

header guard to silence -Wunused-function.

Ganesh Ajjanagadde 80d23d9d32 swscale/swscale: silence unused function warning 
gamma_convert is only used with the old code. Thus, it is
placed under a header guard. This patch silences a -Wunused-function
observed on GCC 5.2.
