tests: Update valgrind suppressions for sw_tree1
This test builds a tree in a previously uninitialized buffer, then writes
the whole buffer out to a file to be used by other tests. Because part of
the buffer may be uninitialized this causes a valgrind error.
Pre-initializing the buffer would remove the error, however it would make
valgrind not notice any accesses to the uninitialized portion *before* the
write out, and those would be genuine errors.
So, instead we use a valgrind suppressions file - however it has a couple
of problems. First it unnecessarily lists the same call path twice.
Second, the call path is only right for some C library versions. Change
the second copy to cover possible path that occurs with a different glibc
version.
