    lpapicache: find binaries from lp

    Also update getBinaries() to allow retreival by binary name

    This significantly speeds up binary file lookup for non-published
    package versions, since we can get the list of binary urls, but
    then have to look up the BPPH for each of those urls, which is slow.
    If the user only wants a specific binary package and/or arch, this
    speeds up getting that, especially for packages with a lot of binary
    files (like the kernel).

That was ages ago though, not sure why this only just broke.

Anyway, seems simple to fix.
