Subject: ghash: Fix signed integer overflow in g_hash_table_set_shift
Shifting 1 by 31 bits triggers a signed integer overflow. Use 1u
for unsigned data type to allow such operation.
Bug: https://gitlab.gnome.org/GNOME/glib/-/issues/672
Origin: upstream, 2.86.1, commit:f8bda4d10990a1e229fc3c3fd09b263ef6f99288
