m/t/installer: deflake by silencing kernel logs

The installer test was failing due to the success flag getting broken
in two by the kernel logs, like this:
>TestOS launched successfully! _TESTOS_LAUNCH_SUC[    0.963289] kvm:
>exiting hardware virtualizationCESS_

This change addresses this problem by setting an adequate loglevel for
both the installer and testos kernels.

m/t/installer/BUILD.bazel now defines its own unified kernel image
target with a custom kernel cmdline needed for test purposes.
