Log message:
Reflect script failure in exit code

installboot(8) runs newfs(8) and fsck(8) via system(3) but only checks
failures of the function itself, always returning zero no matter what the
programs/shell returned.

This is bad for regress tests relying on correct return codes.

create_filesystem() itself must not exit as write_filesystem() calls it and
cleans up temporary files upon failure.

Make it return -1 if the script returned non-zero so write_filesystem()
handles it as error, cleans up and makes installboot exit 1.

Stop ignoring create_filesystem()'s return code in md_prepareboot() and
exit the same way.

Here's the change in behaviour on arm64 (newfs fails because of the
vnd/disklabel race, see "Race in disk_attach_callback?" on tech@):

# installboot -vp vnd0 ; echo $?
newfsing 6694ae5b0d7596ed.i
newfs_msdos: /dev/r6694ae5b0d7596ed.i: No such file or directory

# ./obj/installboot -vp vnd0 ; echo $?
