Subject: [PATCH] sysv-generator: translate "Required-Start" into a "Wants"
 dependency

'Required-Start:' used to be supported by insserv but this functionality was
dropped when insserv was rewritten into a compat perl wrapper (insserv-compat),
which happened when systemd was introduced in SUSE, I guess.

It's been decided to add back the support in systemd instead of insserv-compat,
see the comments in bsc#857204.

[tblume: Port of SLES12SP1 patch 0018-Make-LSB-Skripts-know-about-Required-and-Should.patch]
[fbui: patch sysv-generator-test.py to take this SUSE's specifity into account]

[wfink: fixes bsc#857204]
