TAP driver: cosmetic fixes

* lib/tap-driver.sh: Quote 'like this', not `like this'.  Remove an
obsolete FIXME.  Correctly mark another comment as a TODO rather
than as a FIXME.

maintainer: am-ft: add option to cater to clock skews

* maintainer/am-ft: Add option '-S', giving a number of seconds to sleep
after copying the tarball to the remote system and before unpacking,
building and testing it.  This is to cater to situations where the clock
of the remote system is skewed (in the past) w.r.t. the clock the local
system the tarball has been built on.

tests: remove too-brittle test tap-realtime.sh

* t/tap-realtime.sh: Delete.  It has always been brittle, but now
it's also causing spurious failures when mawk is used as the awk
implementation in tap-driver.sh (see bug#14601).
* t/list-of-tests.mk: Adjust.
