autoconf: do not reference the missing script
Currently, OpenAFS does not use automake. As a result, the missing script
is not copied to the build-tools directory. Since this script is not
present in the tree, am_missing_run is not initialized. Unfortunately,
the current version still has a few references to this variable. In order
to preserve a similar behavior, this commit replaces these references by
AC_ERROR.
While we are changing these, remove the AC_CHECK_PROGS calls for AR and
STRIP, since libtool already checks these for us.
