(enabled by PKG_CONFIG_PATH)

Can't use suppressions as the library may be used by unrelated people
who want valgrind to test _their_ program that utilizes libpmemobj --
they shouldn't get valgrind gripe here.

This code is suboptimal -- it repeats the same disable command in the
most critical part of the read path, affecting non-valgrind use as well.
Needs to be investigated further.
