lint: ignore LINUX_VERSION_CODE

When running the linter against dahdi-linux.git or potentially other
repositories with out-of-tree linux kernel modules, it should not
complain about the LINUX_VERSION_CODE being used there:

> drivers/dahdi/dahdi-base.c:6397: WARNING:LINUX_VERSION_CODE:
> LINUX_VERSION_CODE should be avoided, code should be for the version to
> which it is merged

jobs/{master,gerrit}: eim,ipa: wipe-workspace

Set wipe-workspace for the onomondo-eim and onomondo-ipa jobs to true,
so previous failures cannot influence new jenkins job runs. E.g.
currently we had gerrit-onomondo-ipa-build failing with:

  + mkdir build
  mkdir: cannot create directory 'build': File exists

Most existing jobs call scripts/osmo-clean-workspace.sh from osmo-ci.git
at the beginning of their jenkins.sh instead of using wipe-workspace.
But this doesn't have any advantage here while making jenkins.sh more
complex. Let's use the built-in feature from jenkins here.
