intel-media-driver: dont mark warnings as errors

Switch the driver configuration MEDIA_BUILD_FATAL_WARNINGS to OFF so
-Werror is not used. Also patch out the use of
-Werror=implicit-function-declaration to prevent errors when building
with gcc9.

| cc1plus: error: '-Werror=' argument
'-Werror=implicit-function-declaration' is not valid for C++ [-Werror]
