Use evil merge to fix up grammar mistakes in Kconfig file.

Bad speling and horrible grammar (and copious swearing) is to be
expected, but let's keep it to commit messages and comments, rather than
expose it to users in config help texts or printouts.

+          The config option toggles if a task setting its loginuid requires
+          CAP_SYS_AUDITCONTROL or if that task should require no special permissions
+          but should instead only allow setting its loginuid if it was never
+          previously set.  On systems which use systemd or a similar central
+          process to restart login services this should be set to true.  On older
+          systems in which an admin would typically have to directly stop and
+          start processes this should be set to false.  Setting this to true allows
+          one to drop potentially dangerous capabilites from the login tasks,
+          but may not be backwards compatible with older init systems.
