toolbox/modprobe: Fix failure due to blocklist

When a module is blocklisted, LoadWithAliases() will return an error
indicating the module failed to load. When the blocklist is requested
(via the -b parameter), let's not return an error if a blocklisted
module fails to load.

Test: verified lsmod on pixel 6
