universe: emit warning instead of error for bad/missing KERNCONF
When doing a large `make universe` build with multiple KERNCONFS,
it should not be an error when a particular target has a missing
KERNCONF.
In this example,
```
$ make universe TARGETS='arm64 riscv' KERNCONFS='QEMU VIRT'
```
Currently, arm64 does not have a QEMU conf, and riscv
does not have a VIRT conf. However, this command should still
succeed instead of failing with the following message:
```
make[2]: /usr/src/Makefile:767: Target architecture for riscv/conf/VIRT unknown. config(8) likely too old.
in .for loop from /usr/src/Makefile:761 with kernel = VIRT
in make[2] in directory "/usr/src"
make[2]: stopped making "universe_kernels" in /usr/src
```
Since the opposite is true, we should build whatever confs are available
from the requested list of KERNCONFS, while making sure to still
emit warnings along the way.
