lsm: constify 'file' parameter in security_bprm_creds_from_file()

The 'bprm_creds_from_file' hook has implementation registered in
commoncap. Looking at the function implementation we observe that the
'file' parameter is not changing.

Mark the 'file' parameter of LSM hook security_bprm_creds_from_file() as
'const' since it will not be changing in the LSM hook.
