build: fix build with --enable-minidriver-dummy

Commit 462c012066 ("Add complete JTAG debug logging.") breaks
the build for minidriver, that is enabled either on zy1000 build
and on minidriver-dummy build. The check on BUILD_ZY1000 was added
to pass the auto-build in jenkins. While the build issue with
minidriver-dummy was known, as reported in the comment, it was not
addressed and got ignored for slightly more than one year.

Use the macro HAVE_JTAG_MINIDRIVER_H in place of BUILD_ZY1000 to
take in account both builds that require the minidriver.
Fix also the build in case configure enables the HLA drivers due
to autodetection of libusb. The HLA drivers would not be in the
build and the function transport_is_hla() would be missing.
