Revert "build: disable gir install via list to pacify meson >= 0.60.2 (#98)" (#100)

This reverts commit a4f6cfc.

This commit was wrong, because it tried to work around a bug in a single
version of meson by using something that isn't, wasn't, and won't be a
valid value.

The fixed version of meson 0.60.x has been out for a while now, which
once again accepts `false`, and 0.61.0 also accepts `false` but was
known at the time of this workaround to not work in meson-git master
(now meson 0.61.0).

Using `false` is acceptable and the failure to accept it has been
qualified as a meson regression. Using `[false]` is just... trying to
fuzz meson with random objects until you get something that slips its
way through the argument checker and produces desired effects on the
python implementation level.
