Add a job to generate the release tarball and build/install few

Ideally we should build the 'efi' target from the 'roms' directory,

This job is only triggered when a tag starting with 'v' is pushed,
which is the case with release candidate tags.

Per https://ccache.dev/manual/latest.html:
By default, ccache tries to give as few false cache hits as
possible. However, in certain situations it’s possible that
you know things that ccache can’t take for granted.
[The CCACHE_SLOPINESS environment variable] makes it possible
to tell ccache to relax some checks in order to increase the
hit rate.
We can relax the ctime/mtime header checks:
- include_file_ctime
By default, ccache also will not cache a file if it
includes a header whose ctime is too new. This option
disables that check.
- include_file_mtime
By default, ccache will not cache a file if it includes
a header whose mtime is too new. This option disables
that check.
We also add a call to clear the cache statistics before running
the build, and display them when the build finishes.

Rewrite the implementation of the ssh block driver to use libssh instead
of libssh2. The libssh library has various advantages over libssh2:
- easier API for authentication (for example for using ssh-agent)
- easier API for known_hosts handling
- supports newer types of keys in known_hosts
Use APIs/features available in libssh 0.8 conditionally, to support
older versions (which are not recommended though).
Adjust the iotest 207 according to the different error message, and to
find the default key type for localhost (to properly compare the
fingerprint with).
