vboot: update vboot2 functions to use new vb2_error_t

To make explicit when vboot2 error codes should be returned,
use the new vb2_error_t type on all functions which return
VB2_ERROR_* constants.

Additionally, add required vboot submodule commit id e6700f4c:
    2019-07-31 14:12:30 +0800 - (vboot: update vboot2 functions to use new vb2_error_t)
