Since commit 83aa1baa069c we have been running the build for Coverity
Scan as a Gitlab CI job, rather than the old setup where it was run
on a local developer's machine.  This is working well, but the
absolute paths of files are different for the Gitlab CI job, which
means that the regexes we use to identify Coverity components no
longer work. With Gitlab CI builds the file paths are of the form
 /builds/qemu-project/qemu/accel/kvm/kvm-all.c

rather than the old
 /qemu/accel/kvm/kvm-all.c

and our regexes all don't match.

Update all the regexes to start with .*/qemu/ . This will hopefully
avoid the need to change them again in future if the build path
changes again.

This change was made with a search-and-replace of (/qemu)?
to .*/qemu .
