Merge commit a4ae32c71fe9 ("exec: Always set cap_ambient in cap_bprm_set_creds")
This is a bug fix and one of two places where I have found that the
result of calling security_bprm_repopulate_creds more than once on
different bprm->files depends on all of the bprm->files not just the
file bprm->file.
I intend to fix both of those cases and then modify the code to
only call security_bprm_repopulate_creds on the final bprm file.
So merge this change in so I hopefully reduce conflicts for others
and I make it possible to build on top of this change.
