This patch:
- specializes "linux" scripts into "Ubuntu 18.04" scripts
- renames all future linux blobs on CDN:
* `firefox-linux.zip => firefox-ubuntu-18.04.zip`
* `minibrowser-gtk.zip => minibrowser-gtk-ubuntu-18.04.zip`
* `minibrowser-wpe.zip => minibrowser-wpe-ubuntu-18.04.zip`
* `minibrowser-gtk-wpe.zip => minibrowser-gtk-wpe-ubuntu-18.04.zip`
- updates downloader to deal with the new names

Currently, it might happen that two different patches clash for the
same build number for the browsers. In this case, authors might
not even know that they need to rebaseline.
This patch starts adding a second line to `BUILD_NUMBER` files - the
signature and date of the `BUILD_NUMBER` change. These are guaranteed
to clash, so it should not be possible to land patches without
re-baselining them.
This patch establishes the following convention:
- scripts `checkout_build_archive_upload.sh` and `upload.sh` now accept
build flavor instead of browser name. Build flavor fully defines the
build produced / uploaded.
- scripts under `//browser_patches/webkit` and
`//browser_patches/firefox` produce build that is specific to the host
system.
Both `checkout_build_archive_upload.sh` and `upload.sh` scripts now
accept a `firefox-win64` browser instead of an optional `--win64` flag.
This is a preparation before introducing `webkit-wpe` parameter in these
scripts.
