Revert "Add launchctl_instructions method"

This code makes assumptions about the existence of prefix which are
valid in the context of the installer, but not necessarily in the
context of `brew info`, thus `brew info` on an outdated formula errors
out.

This reverts commit e5b53dd64b769b67805d1054d906f7083939d905.
