OK, let's rerun with some more debugging enabled (DPKG_DEBUG=1 and sed on
dpkg-maintscript-helper to have rm -v and mv -v)

Looks like we have to deal with chained symlinks here:
/usr/share/doc/libvlccore-dev -> libvlccore8 -> vlc-data
This should work with dpkg-maintscript-helper if you use relative
instead of absolute symlinks. "relative" means the output of
readlink $SYMLINK
Absolute means the output from
readlink -f $SYMLINK
must match, which cannot work while switching chained symlinks
to directories.
Don't forget to bump the version.
So for libvlccore-dev.maintscript I'd suggest this (untested):
symlink_to_dir /usr/share/doc/libvlccore-dev libvlccore8 2.2.2-4~
symlink_to_dir /usr/share/bug/libvlccore-dev libvlccore8 2.2.2-4~
Relative symlinks require dpkg 1.17.14, but you already have this
in Pre-Depends (probably generated by debhelper).
