hostbits: fail parse on unexpected trailing data

hostbits: fail parse on unexpected trailing data

Address issue https://redmine.openinfosecfoundation.org/issues/1889
for hostbits. This involves updating the regular expresssion
to capture any trailing data as the regex already keeps
spaces out of the name.

A unit test was converted to new macros to find out which
line it was failing at after updating regex.
