misc/cgo/testcshared: use the gold linker on android/arm64

The gold linker is used by default in the Android NDK, except on
arm64:

https://github.com/android-ndk/ndk/issues/148

The Go linker already forces the use of the gold linker on arm and
arm64 (CL 22141) for other reasons. However, the test.bash script in
testcshared doesn't, resulting in linker errors on android/arm64:

warning: liblog.so, needed by ./libgo.so, not found (try using -rpath or
-rpath-link)

Add -fuse-ld=gold when running testcshared on Android. Fixes the
android/arm64 builder.
