androidtest.bash: correct the location of compiled packages

For android, gc builds with buildmode=pie by default, and
as a result, the compiled packages are not installed in
the usual pkg/$GOOS_$GOARCH pack. Copy the compiled packages
in pkg/android_$GOARCH_shared into the pkg/android_$GOARCH
in the test device.
