CI: Remove libgcc.a linker workaround from repackaged NDK

[Rust 1.68 is now targeting NDK r25] and no longer tries to forcibly
link against `libgcc.a`, which was removed since NDK r23. 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.
