silkworm: disable on incompatible Linux versions (#8893)

Browse Source 
Silkworm built on Ubuntu 22 depends on glibc 2.34. In order to run on an
older OS, Silkworm needs to be built and linked with an older glibc, but
to build on an older OS we need a compatible compiler. Silkworm requires
gcc 11+ that is not available on Ubuntu 20 or Debian 11.

To simplify the deployment disable Silkworm support on versions before
Ubuntu 22, Debian 12, and glibc prior to 2.34. The check for Ubuntu and
Debian is explicit, because some Ubuntu 16 installations report glibc
2.35 with ldd, but `go build` still uses an older system one and fails.
