cros ca: Check venv version based on libraries
Change the version check logic to use the dependent library
file (requirements.in), instead of using the timestamp. With
this change, even the venv has a newer timestamp on the host,
as long as the libraries are the same, DUT won't update the
venv. This will save the venv update time during test.
BUG=b:345846130
TEST=create new venv and ensure there is no update on DUTs
