Allow e_flags as well as e_machine to be computed using the e_machine
helper.
This isn't currently used, the argument is always NULL, but it will be
used for a new header feature.

Pass the e_machine to the kvm functions so that they aren't just wired
to EM_HOST.
In the case of a session move some setup until the session
is created.
As the session isn't fully running the default EM_HOST is returned as no
e_machine can be found in a running machine.
This is, however, some marginal progress to cross platform support.

`perf kvm stat` supports record and report options.
By using the arch directory a report for a different machine type cannot
be supported.
Move the kvm-stat code out of the arch directory and into
util/kvm-stat-arch following the pattern of perf-regs and dwarf-regs.
Avoid duplicate symbols by renaming functions to have the architecture
name within them.
For global variables, wrap them in an architecture specific function.
Selecting the architecture to use with `perf kvm stat` is selected by
EM_HOST, ie no different than before the change.
Later the ELF machine can be determined from the session or a header
feature (ie EM_HOST at the time of the record).
The build and #define HAVE_KVM_STAT_SUPPORT is now redundant so remove
across Makefiles and in the build.
Opportunistically constify architectural structs and arrays.

The util library code is used by the python module but doesn't have
access to the builtin files. Make a util/kvm-stat.c to match the
kvm-stat.h file that declares the functions and move the functions
there.
