BUG: Fix FindBoost versioned find 

To locate the boost include directory, all search paths and versioned
path suffixes should be passed to one call of FIND_PATH.  Previously the
test for one version would find an unversioned system boost even when
the user set BOOST_ROOT (since the NO_DEFAULT_PATH option is not used).
See issue #7456.
