util/futility: Check for pkg-config and libcrypto

When building a configuration that requires futility (e.g. Chrome OS
builds), pkg-config and libcrypto are required. Since vboot's build
system isn't the most helpful about it, test ourselves and fail out
with some actionable message.

Tested:
 - configs that don't need futility don't test for pkg-config, so it's
   not required for them.
 - failing pkg-config test leads to the message
 - working pkg-config test leads to a successful build
