tools/getdelays: use the static UAPI headers from tools/include/uapi

The include directory ../../usr/include is only present if an in-tree
kernel build with CONFIG_HEADERS_INSTALL was done before.
Otherwise the system UAPI headers are used, which most likely are not
the most recent ones.

To make sure to always have access to up-to-date UAPI headers,
use the static copy in tools/include/uapi.
