[sheepdog] [PATCH] tests/functional: use a new variable RANDOM_GEN for _urandom()

[Hitoshi Mitake]

On my ubuntu box (13.04), the openssl command called by _urandom()
dies with segmentation fault (yes, the walkaround was implemented in
the past but the problem occurs again...). For avoiding this problem,
this patch lets _urandom() use a new variable RANDOM_GEN. If this
variable is set, the function uses the variable as a command for
random number generation.
