Always use fnmatch for target wildcard name match

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.

* **Enable basic glob matching of target strings**

  Previously, only the '*' wildcard character would match
  when targets were resolved from areas other than the CLI
  (such as from within a Plan).  With this change wildcard
  matching is switched to use Ruby's fnmatch with basic
  glob matching enabled.  In addition to providing more
  wildcard matching options, it also provides a significant
  performance improvement over the prior implementation.
