main/glib: revert move quark initialization to a contructor

building gobject-introspection fails without this fix:

assertion 'hash_table != NULL' failed
GLib-GObject:ERROR:gtype.c:2747:g_type_register_static:

+Subject: [PATCH] Revert "Move quark initialization to a constructor"
+
+musl's does not run ctors in the assumed order that glib-2.46 expects:
+
+- glib_init() should be called before gobject_init_ctor().
+
+This reverts commit 2fe992b099bfd3fb121a71b7af43e116b2142b5d.
