subprocess: Log subprocess arguments when running

Utility programs in vboot sometimes use subprocess_run to execute
another program like flashrom or cbfstool. This change makes it easier
to debug these utilities by logging executed subprocess and its
arguments.

This change also fixes futility vb2ex_printf() implementation.
Previously use of VB2_DEBUG_RAW() calling vb2ex_printf(NULL, ...) was
unnecessarily trying to print NULL as function name, which was not
intended behavior.

TEST=sign image and look for "Run: cbfstool ..."
BUG=none
BRANCH=none
