tests: fix a memory leak

Browse Source 
This has been bugging me for while.  I was hard to reproduce: it
worked only on GNU/Linux, probably because libc++ implements the small
string optimization, while libstdc++ did not and actually allocated on
the heap for this small string.

See https://lists.gnu.org/archive/html/bison-patches/2018-09/msg00110.html.

* tests/types.at (api.value.type): Do not provide a semantic value to
EOF.
