No longer consider Ubuntu Bionic as a supported build platform

According to https://wiki.ubuntu.com/Releases, Bionic reaches "End of Standard Support" in April.

OTOH, it does not mean "End of Life" as it is expected 5 years later, in April 2028.

In terms of Canonical's support, it makes Bionic the same as Xenial and Trusty releases.

In Bionic both default compilers, GCC and Clang, are too old to compile Bitcoin Core: GCC 7.5 and Clang 6.0.
