oeqa: qemu: ensure that host dump commands can be run properly

If runqemu fails, there is some logic to run a set of commands to dump
various bits of information that might help debug the issue
(particularly in a busy situation such as on the autobuilder). However,
when we try to run these we are inside the normal build environment
which restricts commands to be run on the host to those specified in
HOSTTOOLS. Since this isn't a place where host contamination is going to
be a problem, override PATH to a reasonable default so that we run the
actual host tools directly to avoid the issue. (Logically we would want
to use the original PATH value here, but it is not easily accessible.)
