[PULL 13/20] avocado/ppc_prep_40p.py: check TCG accel in all tests

[Cédric Le Goater]

From: Daniel Henrique Barboza <danielhb413@gmail.com>

All tests in the file times out when running in an IBM POWER host and
--disable-tcg with an error like the following:

        Command: ./qemu-system-ppc -display none -vga none (...)
-machine 40p (...)
        Output: qemu-system-ppc: Register sync failed... If you're using
kvm-hv.ko, only "-cpu host" is possible
qemu-system-ppc: kvm_init_vcpu: kvm_arch_init_vcpu failed (0): Invalid argument

Since we don't have a way to detect whether the host is running kvm_hv
or kvm_pr, skip all tests if TCG is not available.
