vsock/test: Do not filter kallsyms by symbol type 

[ Upstream commit 5d54aa40c7b7e9dee5746cca99e9ddbcca13e895 ]

Blamed commit implemented logic to discover available vsock transports by
grepping /proc/kallsyms for known symbols. It incorrectly filtered entries
by type 'd'.

For some kernel configs having

    CONFIG_VIRTIO_VSOCKETS=m
    CONFIG_VSOCKETS_LOOPBACK=y

kallsyms reports

    0000000000000000 d virtio_transport	[vmw_vsock_virtio_transport]
    0000000000000000 t loopback_transport

Overzealous filtering might have affected vsock test suit, resulting in
insufficient/misleading testing.

Do not filter symbols by type. It never helped much.
