Subject: MDEV-11718 5.5 rpl and federated tests massively fail in buildbot
 with valgrind

Problem:- When MariaDB is compiled with jemalloc support, And we run mtr valgrind
test, valgrind interferes with libjemalloc and returns false errors.

Solution:- Run valgrind with --soname-synonyms=somalloc=libjemalloc* or
--soname-synonyms=somalloc=NONE depending on whether we are dynamically
linking or statically linking.
