FGLWRTUMASK removal

The FGLWRTUMASK environment variable is no longer supported.

Before BDL 4.00 (using FLM 5), the FGLWRTUMASK environment variable could be defined to specify a Unix file permission mask for the FGLDIR/lock directory creation.

Starting with BDL 4.00 (now using FLM 6), the FGLWRTUMASK environment variable is no longer supported and the FGLDIR/lock directory will be created with rwxrwxrwx Unix file permissions.
