cvtsudoers: merge aliases when multiple sudoers files are specified

Browse Source 
Duplicate aliases are remove.  If there are conflicting alias names,
the conflicts are renamed by appending a numerical suffix.
For example, if there are two SERVERS Host_Aliases, the second one
will be renamed to SERVERS_1.
