  Fix some build and test failures with Autoconf 2.70.
  
  Autoconf 2.70 (released last week) makes a few changes that broke Automake’s
  expectations, mostly in the test suite.  This patch addresses two of the
  problems:
  
   - autoconf now issues a warning if fed a configure script that doesn’t invoke
     both AC_INIT and AC_OUTPUT; this, plus a problem with system-provided
     tools (still under investigation) broke the *build* on macOS; it also
     causes a couple of spurious testsuite failures.
  
   - AC_PACKAGE_NAME and AC_PACKAGE_VERSION are now defined unconditionally.
     AM_INIT_AUTOMAKE needs to use m4_ifset instead of m4_ifdef to diagnose
     the obsolete use of AC_INIT with fewer than two arguments.  (This change
     is compatible with autoconf 2.69; m4_ifset is much older, and it means
     ‘defined with a non-empty value’.)
  
  * configure.ac: Use both AC_INIT and AC_OUTPUT in test configure scripts.
  * t/deprecated-acinit.sh, t/init.sh: Likewise.
  * m4/init.m4 (AM_INIT_AUTOMAKE): Use m4_ifset, not m4_ifdef, to detect
    AC_PACKAGE_NAME and/or AC_PACKAGE_VERSION not having a value.
