Install kernel-devel package in install_ltp

[mdoucha]

The KLP test requires kernel-devel package to work. Install it together with kernel in install_ltp job to prevent KLP test from failing due to cleared incident repository. KOTD tests in particular are prone to failing because their incident repo gets cleared more than once a day.

• Needles: N/A
• Verification runs:
  • KOTD install: https://openqa.suse.de/tests/3544758
  • KOTD KLP: https://openqa.suse.de/tests/3546051
  • dtb-aarch64 install: https://openqa.suse.de/tests/3559521
  • dtb-aarch64 KLP: https://openqa.suse.de/tests/3559582
  • kgraft install: https://openqa.suse.de/tests/3604905
  • kgraft KLP: https://openqa.suse.de/tests/3604916
  • azure install: https://openqa.suse.de/tests/3580410

(This will take a while because there are currently no incident repos for some verification runs.)

LGTM. It might be needed also in install_ltp in case of git installation (well, that installation is now sort of deprecated).

All verification runs passed, this PR is ready for merge.

Unfortunately this breaks tests:
http://quasar.suse.cz/tests/4028 which don't take install_ltp as kernel-devel isn't installed, see:
http://quasar.suse.cz/tests/4028/file/serial_terminal.txt

It might be possible to install, but it's difficult to find the version:

$ uname -r
4.12.14-197.21-default

$ uname -r | sed 's/-default//'
4.12.14-197.21

$ zypper se -s kernel-default-devel |grep $(uname -r | sed 's/-default//') | awk '{print $6}'
4.12.14-197.21.1

So, not sure how to fix it.

[pevik]

OK, maybe this could work
rpm -qf /boot/config-$(uname -r) | sed 's/-default-/-default-devel-/'

Where did the disk image for that test come from?

[pevik]

OK, resolved with mdoucha as temporary issue (image was created before merge so kernel-devel isn't installed. Will be fixed for next KOTD, that one will install kernel devel together with LTP).
