ima_bprm_check - based on policy, collect/store measurement. : contains the linux_binprm structure

The OS protects against an executable file, already open for write, from being executed in deny_write_access() and an executable file, already open for execute, from being modified in get_write_access(). So we can be certain that what we verify and measure here is actually what is being executed.

Return 0 on success, an error code on failure. (Based on the results of appraise_measurement().)
