0e3901891a docs: SafeSetID.rst: Remove spurious '???' characters
It appears that some smart quotes were changed to "???" by even smarter
software; change them to the dumb but legible variety.

aeca4e2ca6 LSM: add SafeSetID module that gates setid calls
SafeSetID gates the setid family of syscalls to restrict UID/GID
transitions from a given UID/GID to only those approved by a
system-wide whitelist. These restrictions also prohibit the given
UIDs/GIDs from obtaining auxiliary privileges associated with
CAP_SET{U/G}ID, such as allowing a user to set up user namespace UID
mappings. For now, only gating the set*uid family of syscalls is
supported, with support for set*gid coming in a future patch set.
