Previously the list of services and characteristics wasn't sorted, and
because of the way Go maps work they were in fact randomized.
This commit fixes the sorting for services and characteristics, which
both suffered from the same lack of sorting.
This fixes https://github.com/tinygo-org/bluetooth/issues/135.
This is very much like https://github.com/tinygo-org/bluetooth/pull/161,
but for Linux instead. In fact, I've copied the structure of the code
because it works for macOS.
I have tested that the scan order is now as requested. I also verified
that multiple characteristics with the same UUID are now supported, but
support is still a bit buggy: they appear in a random order (due to Go
map iteration order). I will fix this in the next commit.
