Subject: [PATCH 1/1] pid1: handle console specificities/weirdness for s390
 arch

The 3270 console on S/390 can do color but not the 3215 console.

Partial forward port of
0001-On_s390_con3270_disable_ANSI_colour_esc.patch from SLE12-SP1. A
bunch of the previous code has been dropped since some changes
imported from upsteam made them uneeded.

The remaining bits are probably hackish but at least they are now
minimal.

It was an attempt to address bnc#860937 to automatically turn the console color
mode off by passing $TERM=dumb when the specified terminal device is other than
"3270". For more details, see
https://www.ibm.com/docs/en/linux-on-systems?topic=setup-kernel-parameters.

See also a short discussion which happened on @systemd-maintainers
whose $subject is "[PATCH] support conmode setting on command line".

[fbui: fixes bsc#860937]

Don't warn if "conmode=" is missing as this option should not be passed on
s390x KVM.

[fbui: fixes bsc#1236725]
