scripts/install-buildtools: add helper script to install buildtools

For distros such as CentOS-7 where the default buildtools are too
old we need to make it easy for users to install a pre-built SDK
with all of "build-essentials" included.

Other uses may include building older Yocto Project releases with
a distro where buildtools are too new.

For convenience, the standard buildtools installation is also
supported.

NOTE: extended buildtools is the default, e.g.
      --with-extended-buildtools is on by default

Example usage (extended buildtools from milestone):
  (1) using --url and --filename
      $ install-buildtools \
        --url http://downloads.yoctoproject.org/releases/yocto/milestones/yocto-3.1_M2/buildtools \
        --filename x86_64-buildtools-extended-nativesdk-standalone-3.0+snapshot-20200122.sh
  (2) using --base-url, --release, --installer-version and --build-date
      $ install-buildtools \
        --base-url http://downloads.yoctoproject.org/releases/yocto \
        --release yocto-3.1_M2 \
        --install-version 3.0+snapshot
        --build-date 202000122

Example usage (standard buildtools from release):
  (3) using --url and --filename
      $ install-buildtools --without-extended-buildtools \
        --url http://downloads.yoctoproject.org/releases/yocto/yocto-3.0.2/buildtools \
        --filename x86_64-buildtools-nativesdk-standalone-3.0.2.sh
  (4) using --base-url, --release and --installer-version
      $ install-buildtools --without-extended-buildtools \
        --base-url http://downloads.yoctoproject.org/releases/yocto \
        --release yocto-3.0.2 \
        --install-version 3.0.2
