sudo: Update to version 1.9.15p4

- Update from version 1.9.15p2 to 1.9.15p4
- Update of rootfile not required
- Changelog
    1.9.15p4
	 * Fixed a bug introduced in sudo 1.9.15 that could prevent a user's
	   privileges from being listed by "sudo -l" if the sudoers entry
	   in /etc/nsswitch.conf contains "[SUCCESS=return]".  This did not
	   affect the ability to run commands via sudo.  Bug #1063.
    1.9.15p3
	 * Always disable core dumps when sudo sends itself a fatal signal.
	   Fixes a problem where sudo could potentially dump core dump when
	   it re-sends the fatal signal to itself.  This is only an issue
	   if the command received a signal that would normally result in
	   a core dump but the command did not actually dump core.
	 * Fixed a bug matching a command with a relative path name when
	   the sudoers rule uses shell globbing rules for the path name.
	   Bug #1062.
	 * Permit visudo to be run even if the local host name is not set.
	   GitHub issue #332.
	 * Fixed an editing error introduced in sudo 1.9.15 that could
	   prevent sudoreplay from replaying sessions correctly.
	   GitHub issue #334.
	 * Fixed a bug introduced in sudo 1.9.15 where "sudo -l > /dev/null"
	   could hang on Linux systems.  GitHub issue #335.
	 * Fixed a bug introduced in sudo 1.9.15 where Solaris privileges
	   specified in sudoers were not applied to the command being run.
