AC_HEADER_ASSERT: don't say assertions are disabled when they're not

Browse Source 
* lib/autoconf/headers.m4 (AC_HEADER_ASSERT): Do not make configure
report "checking whether to enable assertions... no", when they are
in fact enabled.  This is solely a bug in the output of configure.
In spite of saying "no", NDEBUG was not defined in that case.
Also, as noted by Eric Blake, leave assertions enabled upon
--enable-assert=INVALID.
