apps: Update transport selection method

Transport package should not be included directly.
Instead, nimble/transport should be included and
BLE_HCI_TRANSPORT syscfv value should specify transport,
and this will include correct package.

This commit changes nimble/transport/ram to nimble/transport in
all applications that still have deprecated way of transport
selection.
