libxml2: Add bash dependency for ptests.
Before, running ptests on core-image-minimal would result in
an error due to missing /bin/bash:
[ -d test ] || ln -s ../libxml2-2.9.10/test .
make: /bin/bash: No such file or directory
make: *** [Makefile:2105: runtests] Error 127
Changing the Makefile to use /bin/sh results in some of the
tests failing, so I have added the missing dependancy on bash.
