file caps: always start with clear bprm->caps_*
While Linux doesn't honor setuid on scripts. However, it mistakenly
behaves differently for file capabilities.
This patch fixes that behavior by making sure that get_file_caps()
begins with empty bprm->caps_*. That way when a script is loaded,
its bprm->caps_* may be filled when binfmt_misc calls prepare_binprm(),
but they will be cleared again when binfmt_elf calls prepare_binprm()
next to read the interpreter's file capabilities.
