with lvm_type=thin parsing of lvm version fails

[Giulio Fidente]

supports_thin_provisioning fails on customised builds; RHEL for instance reports version as:

2.02.100(2)-RHEL6

    improves lvm version parsing for customised builds

    supports_thin_provisioning now uses a regexp to ensure parsing of
    lvm version succeeds when the build is customised; also adds a test
    for a customised string parsing
