Improve inventory target name resolution performance

When resolving a large number of targets from a plan the
match_wildcard? regex is compiled on the fly possibly
hundreds or thousands (for a large inventory) of times
per target name resolution.

Switching to File.fnmatch provides a significant speed
increase and seems to more accurately reflect the
functionality stated in the Bolt documentation with
regards to target matching.
