Fix error when build base component

Amend Xilinx#8706. Use dummy value or XRT_DEV_COMPONENT when building only
base component.

Tempoary fix for cpackLin conditionally adding dependencies for
legacy XRT when XRT_DEV_COMPONENT equals "xrt".  We don't want the
dependencies in case of base package so use dummy value to by-pass.

Also, ensure that pcie/linux shim is built only when XRT_BASE is
active.  Linux shim is shared between npu and alveo, hence should be
in base component only.
