Replace the inline awk script with a Perl script which tracks the dependencies recursively. This allows to correctly track dependencies for files including files with a second level include (for example: ffmpeg-devices.texi -> devices.texi -> outdevs.texi). This also adds a dependency on perl for computing the dependencies, which should not be a problem since perl is already required all the way for building documentation. This is a variant of commit 628ceac6 which was reverted due to out-of-tree build failure.
