Subject: [PATCH] sysv-generator: initialize LookupPaths just once
With debugging on, sysv-generator would print the full set of
lookup paths for *every* sysv script.
While at it, pass LookupPaths as a pointer in sysv-generator,
and constify it everywhere.
(cherry picked from commit a8ffe6fbcbfdba39aef8dce8b298b3e0cb377c0e)
