bitbake/utils: Add contains helper function from lib.oe.utils

This function is needed by some of the early .conf setup we need
to improve the machine/tune files in Openembedded. We need to add
it here since the location in oe.utils can't be accessed until after
base.bbclass parses which is too late for our needs.
