populate_sdk_ext: install the latest buildtools-tarball

If we do `bitbake buildtools-tarball' and then after one day do `bitbake
core-image-minimal -c populate_sdk_ext', we would meet errors like below.

| install: cannot stat '/buildarea2/chenqi/poky/build-systemd/tmp/deploy/sdk/
poky-glibc-x86_64-buildtools-tarball-core2-64-buildtools-nativesdk-standalone
-1.8+snapshot-20150429.sh': No such file or directory

The problem is that the output name for buildtools-tarball has ${DATE} in it.
So if populate_sdk_ext task is executed but buildtools-tarball is not rebuilt,
the above error appears.

Instead of hardcoding ${DISTRO_VERSION} which consists of ${DATE} in the
install_tools() function, we should find the latest buildtools-tarball based
on the modification time and install it.
