Let's add a testcase for a S390 system running kernel version 4.14 on
LPAR.

Some ARM platforms, such as the original Raspberry Pi, report the
CPU frequency in the BogoMIPS field of /proc/cpuinfo, so libvirt
parsed that field and returned it through its API.
However, not only many more boards don't report any value there,
but several - including ARMv8-based server hardware, and even the
more recent Raspberry Pi 3 - use this field as originally intended:
to report the BogoMIPS value instead of the CPU frequency.
Since we have no way of detecting how the field is being used,
it's better to report no information at all rather than something
ludicrous like "your shiny 96-core aarch64 virtualization host's
CPUs are running at a whopping 100 MHz".

Make the parser both more strict, by not ignoring errors reported
by virStrToLong_ui(), and more permissive, by not failing due to
unrelated fields which just happen to have a know prefix and
accepting any amount of whitespace before the numeric value.

Bit more test data, this time with complete info copied, mainly with
cache information, so we can easily add tests for it.

The functionality these tests partially relied on (scanning the cpu
directory for cpu[0-9]+ subdirectories) is going to be removed, so we
need additional files that are present on all non-medieval systems.
Removing all these tests would be an option but we would lose the
ability to test the topologies. Even though we just extract number of
sockets/cores/threads from all these directory trees.
