Subject: [PATCH] fix(gix-index): handle loongarch64-musl stat struct field
 names

On `loongarch64-unknown-linux-musl` with musl 1.2.3+, the libc `stat`
struct uses POSIX timespec fields (`st_mtim`, `st_ctim`) instead of
separate seconds and nanoseconds fields (`st_mtime`, `st_mtime_nsec`).

This was exposed by libc 0.2.180 which added proper time64 support for
this target, causing compilation failures in rust-lang/rust CI.

Fixes the same pattern already used for AIX and Hurd targets.
