Joseph Heenan 7fdd210543 Produce more helpful error if pkg-config not installed
Currently if users run autoreconf then configure without having
pkg-config installed, they see:

./configure: line 5283: syntax error near unexpected token FFMPEG,'
./configure: line 5283:    PKG_CHECK_MODULES(FFMPEG, libavutil
libavformat libavcodec libswscale, HAVE_FFMPEG=yes)'

This is not hugely helpful and causes support queries and confusion.
It is because the pkg.m4 file that defines PKG_CHECK_MODULES is not
available of pkg-config is not installed.

To work around this, remove PKG_CHECK_MODULES and do roughly the
equivalent calling pkg-config directly. To mirror the current
behaviour, we also add a test for pkg-config being present and abort
if it is not. (I am not 100% sure this is the desired behaviour, but
regardless this commit is still an improvement on what we currently
have.)
