hostname: fix behavior when in jail.
Only -d and -f should cause a DNS lookup. The rest should just act directly on the result of gethostname(3). Encountered with the AOSP buildbots' use of nsjail, but tested with both the Debian hostname and toybox hostname thus: ``` unshare -Uunr sh hostname android-build hostname hostname -s hostname -d hostname -f ``` (Not sure how to add that to the tests.) Also fix a SEGV with -s if the hostname doesn't contain a '.'. Also switch to the FLAG() macro. Also add the missing -s to the synopsis. Bug: http://b/123123255
