artiq_flash: explicitly pass path within conda env to openocd dataroo…

…tdir. By default, openocd searches for scripts in DATAROOTDIR/openocd/scripts. This of course makes it not relocatable. Conda has a flag to try to detect and fix such hardcoded paths, but it does not work on openocd (likely because the .rodata contains an already concatenated path, which cannot be padded with zeroes from the right). So, we pass the path explicitly instead.
