libvirt: fix build error caused by host 'xmllint'

There is host contamination in that we force XMLLINT to be
'/usr/bin/xmllint' via ac_cv_path_XMLLINT. This results in the error:

    /bin/bash: /usr/bin/xmllint: No such file or directory

We only use XMLLINT during the build, it is present in two Makefiles
included with ptest package but they are unused. So we drop the
setting of ac_cv_path_XMLLINT to ensure we are using xmllint in the
recipe sysroot instead of the host's. Should the ptest package ever
evolve to make use of the Makefiles we need to update not only the
XMLLINT path but that for XSLTPROC and others too. (I would suggest
that the Makefiles may have been used on the target as part of ptest
at one point, but are no longer and should be removed, though I
haven't investigated further).
