fix equery bash autocomplete

An unintended consequence of I186e14ac4b9e823885c0a7c7f4177603cbf3e682
is that filenames are no longer autocompleted when being entered as the
second CLI argument to equery. This CL reenables default autocompletion
for arguments after the first argument.

BUG=None
TEST=in chroot, enter `equery belongs [tab][tab]`. See autocomplete list
of files.
