CI: Remove libgcc.a linker workaround from repackaged NDK

[Rust 1.68 is now targeting NDK r25] instead of r17 and no longer tries
to forcibly link against `libgcc.a`, which was removed since NDK r23 in
favour of [only needing to link against `libunwind`].  Since this Rust
release is over 1.5 years old, assume everyone is using at least 1.68
and drop the workaround from our repackaged NDK release.
