rust: fix bindgen build error with UBSAN_BOUNDS_STRICT
With commit 2d47c6956ab3 ("ubsan: Tighten UBSAN_BOUNDS on GCC") if
CONFIG_UBSAN is enabled and gcc supports -fsanitize=bounds-strict, we
can trigger the following build error due to bindgen lacking support for
this additional build option:
BINDGEN rust/bindings/bindings_generated.rs
error: unsupported argument 'bounds-strict' to option '-fsanitize='
Fix by adding -fsanitize=bounds-strict to the list of skipped gcc flags
for bindgen.
Fixes: 2d47c6956ab3 ("ubsan: Tighten UBSAN_BOUNDS on GCC")
