[PATCH v6 3/5] binman: ti_secure: drop the redundant keyfile re-read

[Sergio Prado <sergio.prado@e-labworks.com>]

Entry_ti_secure and Entry_ti_secure_rom both call super().ReadNode() and
then read the 'keyfile' entry argument a second time, with exactly the
call that Entry_x509_cert.ReadNode() has already made. The second read is
pure duplication, and it means anything the parent does to
self.key_fname is silently discarded.

Drop it, so that the subclasses use the value their parent decided on,
and drop the EntryArg import which becomes unused.

No functional change.
