When using "-f x11grab -i :0.0" valgrind reports a definitely lost
memory block with this message:
==31544== 5 bytes in 1 blocks are definitely lost in loss record 1 of 2
==31544== at 0x4026E68: memalign (in /usr/lib/valgrind/vgpreload_memcheck-amd64-linux.so)
==31544== by 0x4026F17: posix_memalign (in /usr/lib/valgrind/vgpreload_memcheck-amd64-linux.so)

==31544== by 0x60D3A70: av_strdup (in /usr/lib/x86_64-linux-gnu/libavutil.so.51.22.1)

The 5 bytes lost are the ones from param = av_strdup(":0.0"), so let's
free param in the exit path.
Also check the av_strdup() return value.
Note: calling av_free(param) even when av_strdup() fails and param is
NULL is OK and keeps the code simpler without adding another label to
skip av_free().
