scripts/install-buildtools: write download URLs to files for traceability

This extends the previous commit, so that download URLs are preserved
in addition to actual artefacts. By default it's all written to a temporary
directory and erased together with artefacts, but users can choose
to preserve both:

$ install-buildtools -D --downloads-directory=.
...

$ ls -1
buildtools_url
checksum_url
x86_64-buildtools-extended-nativesdk-standalone-5.1.2.sh
x86_64-buildtools-extended-nativesdk-standalone-5.1.2.sh.sha256sum

Additionally, rename check_url variable into checksum_url as it's
a better name.
