[sheepdog] [PATCH 1/3] tests/functional: add support for specifying valgrind options

[MORITA Kazutaka]

From: MORITA Kazutaka <morita.kazutaka at lab.ntt.co.jp>

This enables us to run valgrind with user defined options.

For example, to do the valgrind test on the small memory (less than 2
GB) machine, try the following command:

 # VALGRIND_OPTIONS="--freelist-vol=10000000 --freelist-big-blocks=0" ./check -valgrind
