The libdir changes to use /usr/lib{32,64} instead of /usr/lib broke
cross builds for some packages that use gir, due to issues with copying
over symlinks. Since we haven't managed to track down the root cause for
the installation path, a symlink is a clean enough temporary fix. This
follows the style of the 00-libdir hooks.
Since pre-install runs for the main package and then each subpackage, it
should use PKGDESTDIR (not DESTDIR), which also enables a subpackage
that installs files during pkg_install to work cleanly.
As far as I can see, the previous hook was quite flawed. Since it was a
pre-install hook, the check for a directory would happen *before*
package installation (so nothing would happen). The only reason it did
anything was because it also ran as a step before a subpackage's
pkg_install (most GIR packages have a -devel subpackage), but used
DESTDIR instead of PKGDESTDIR, so it checked and affected the contents
of the main package. Then when the subpackage's pkg_install ran, the
files would have already been copied to the correct folders.

COPYING says
ALTERNATIVELY, this product may be distributed under the terms of
the GNU General Public License, in which case the provisions of the GPL2
are required INSTEAD OF the above restrictions. (This clause is
necessary due to a potential bad interaction between the GPL and
the restrictions contained in a BSD-style copyright.)

Closes: #28073
Due to constant change in vala, some projects includes some old and
pre-generated vapi in their source tree and uses that version
instead of system one.
Pass system vapidir after real arguments in order to prefer its bundled
vapi.
