[PATCH RFC v2 09/11] ti: x509: Remove shell script used for signing

[Neha Malcom Francis <n-francis@ti.com>]

Earlier the k3_gen_x509_cert.sh was used for signing binaries with the
x509 certificate for Texas Instruments K3 architecture devices. Since
the signing process is handled by x509 etype now, there is no more
requirement for this script, hence removing it.
