bug#23307: VLC does not build deterministically

Commit 4ef2721b52c4929aac15db4f8b39702cd37955a1 fixed an obvious
timestamp-related reproducibility issue in VLC 2.2.1, but there remains
a problem with the ‘lib/vlc/plugins/plugins.dat’ whose contents differ
across rebuilds by a few 32-bit values (see attached diffoscope output.)

The ‘plugins.dat’ file is generated by this rule in bin/Makefile.am:

--8<---------------cut here---------------start------------->8---
../modules/plugins.dat: vlc-cache-gen$(EXEEXT)
        $(AM_V_at)rm -f ../modules/plugins.dat
        $(AM_V_GEN)if test "$(build)" = "$(host)"; then \
                ./vlc-cache-gen$(EXEEXT) ../modules ; \
        else \
                echo "Cross-compilation: cache generation skipped!" ; \
        fi
--8<---------------cut here---------------end--------------->8---
