Set 'is_root' if the node has been opened by the root user (this was
the old behavior) or if it has been opened by the user the translator
is executing under.
This fixes the irritating bug that an unprivileged user cannot control
her own trivfs-based translators. It does not change how privileged
trivfs translators work.
* libtrivfs/io-reauthenticate.c (trivfs_S_io_reauthenticate): Use the
new function to compute 'isroot'.
* libtrivfs/io-restrict-auth.c (trivfs_S_io_restrict_auth): Likewise.
* libtrivfs/open.c (trivfs_open): Likewise.
* libtrivfs/priv.h (_is_privileged): New function.
* libtrivfs/trivfs.h (struct peropen): Clarify what 'isroot' means.

initialization.
