Rolf Neugebauer a8cc4f4f42 kernel: Don't compile -rt kernels on s390x 
Looks like commit 9a88a5e986 ("Upgrade -rt patches to
v4.14.29-rt25") accidentally added compiling -rt kernels
for s390x. Remove it.

# This builds the supported LinuxKit kernels. Kernels are wrapped up
# in a scratch container, which contains the bzImage, a tar
# ball with modules, the kernel sources, and in some case, the perf binary.
#
# Each kernel is pushed to hub twice:
# - linuxkit/kernel:<kernel>.<major>.<minor>-<hash>
# - linuxkit/kernel:<kernel>.<major>.<minor>
# The <hash> is the git tree hash of the current directory. The build
# will only rebuild the kernel image if the git tree hash changed.
#
# For some kernels we also build a separate package containing the perf utility
# which is specific to a given kernel. perf packages are tagged the same way
# kernel packages.
