PATCH 1/1 classes/package: handle filenames containing wildcards

It is uncommon, but it is possible for upstream sources to contain files that have wildcard characters in their names (Webmin is an example). Because we were running glob.glob() on every entry in the list of entries in FILES and then adding the result to the files list to be processed, the process would loop infinitely if files whose names contained wildcard characters were present. Fix this by avoiding re-processing the output of glob.glob() with itself, and also "escape" wildcard characters in FILES entries added automatically from do_split_packages().

Fixes [YOCTO #1676].
