[tests/memory.c] Call "fflush (NULL)" before abort() in order to flush

all the output streams, in particular the log file (when there is one),
so that setting MPFR_LOG_FLUSH (which may be inefficient) is not needed
to debug tests that end with a memory error.

This fixes a regression with glibc 2.27+: the streams are no longer
flushed by abort(), as permitted by POSIX; see the abort(3) man page.
