configure.ac: rename 'adapterTuple' as 'adapter_driver'

Commit ce3bf66 ("configure.ac: rename M4 macro 'adapter' to
prevent accidental conflicts") renames the macro as 'adapterTuple'
but since the macro name is printed in error messages, this
creates cryptic errors like:
	configure: error: header sys/mman.h is required
	for adapterTuple "Bitbanging on EP93xx-based SBCs".

Rename it as 'adapter_driver'. It keeps valid the purpose of the
former renaming, while keeping readable the error message.
