cover CentOS 5.x fixes

A few fixes I made in the process of testing builds on CentOS 5.7.

PATCH 1/3 qemu: for native, do not fail if kvm is unavailable

When building qemu-native, if the linux kvm header is unavailable (as it is on CentOS 5.x 32-bit) then do not pass the --enable-kvm switch to the configure script, thus avoiding failed do_configure.

PATCH 2/3 scripts/runqemu: show an error if /dev/net/tun is unusable

In reply to Paul Eggleton

If /dev/net/tun is either not present or is not writable by the user, then show an appropriate error message. (QEMU needs access to this device in order to enable networking; it may be missing if it is not enabled or loaded into the kernel, and some distributions such as CentOS 5.x set restrictive permissions upon it.)

PATCH 3/3 scripts/bitbake: add a version >= 2.6 check

In reply to Paul Eggleton

Unfortunately we now have code in BitBake which is parsed before the current version check and is incompatible with Python < 2.6. Rather than fixing this and being eternally vigilant for >= 2.6 feature usage, just add a version check to the wrapper script.
