[libvirt] [PATCH] build: fix autobuild failures on gcov upgrade

[Eric Blake]

* autobuild.sh: Avoid syntax error on failed test.
* tools/Makefile.am (CLEANFILES): Clean coverage files.
---

Pushing under the build-breaker rule.  Last time I ran ./autobuild.sh
was on F13; and upgrading to F14 exposed these leftovers due to a
newer gcov than what was in the stale files, in the form of spurious
messages that break 'make check':

+profiling:/home/remote/eblake/libvirt-tmp/tools/virsh-console.gcda:Version mismatch - expected 405R got 404R

and concluding with a bug in the autobuild.sh script itself:

./autobuild.sh: line 44: test: =: unary operator expected
