[shac] Make default clang-format tool parameter a function call.
In fuchsia.git, shac checks need access to the 'ctx' variable
in order to determine the location of the prebuilt tools.
This changes the default tool parameter from a string to
a lambda, so this check can be used in both environments.
Tested by pinning this change in fuchsia.git and running the tools.
