Add patch for CVE-2026-58010 which fixes an off-by-one error
in the GVariant tuple serialiser's normal form checking code.
The bug allowed a single byte out-of-bounds read when verifying
padding bytes in a short (non-normal) tuple. The patch changes
the offset comparison from `>` to `>=` in
gvs_tuple_is_normal() and adds a regression test. An additional
fix includes `<stdint.h>` in the test file so that the new test
using `uint8_t` compiles correctly against the older glib 2.80.4
codebase.
