On ppc64le, the accel.kvm_available() check may wrongly
return False because the host arch (as returned by os.uname[4])
and the target arch (ppc64) mismatch. In order to solve this
it is added an ppc64le -> ppc64 mapping which is used as an
fallback verification.

Currently kvm_available() checks for the presence of kvm module
and, if target and host arches don't mismatch. This patch adds
an 3rd checking: if QEMU binary was compiled with kvm
support.

Since commit cbe6d6365a48 the command `qemu -accel help` returns
the list of accelerators enabled in the QEMU binary. This adds
the list_accel() method which return that same list.

This creates the 'accel' Python module to be the home for
utilities that deal with accelerators. Also moved kvm_available()
from __init__.py to this new module.
