policycoreutils: semanage: skip comments while reading external configuration files

Browse Source 
Fix fcontextRecords() in policycoreutils/semanage/seobject.py so
that semanage does not produce an error in fcontext mode when
the file_contexts.subs_dist file contains comments (prefixed by #).

Properly skip blank lines.

Treat both white space and tab as valid separators for the above
mentioned policy configuration file (v2). Minimum number of
changes (v2bis).
