utils/multiprocess_launch: Improve failing subprocess output

After this patch:
ERROR: bash-4.4.18-r0 do_package_write_ipk: Fatal errors occurred in subprocesses:
Command 'PATH="X" opkg-build -Z xz -a "--memlimit=50% --threads=88" Foobar /media/build1/poky/build/nodistro-glibc/work/core2-64-oe-linux/bash/4.4.18-r0/deploy-ipks/core2-64' returned non-zero exit status 1.
Subprocess output:Foobar
*** Error: Package name Foobar contains illegal characters, (other than [a-z0-9.+-])
opkg-build: Please fix the above errors and try again.
We suddenly get a much more usable error message. The traceback is supressed
as its distracting from the real problem in this case.
Ideally python itself would handle this but it doesn't so we have to
wrap the exception. We already do this in bitbake itself for the same reason.
