tinyalsa: bump version to 1.0.2

tinyalsa has started doing release, so we will use it.

With this release, both our patches were applied mainline:
    - 0001-tinypcminfo-make-function-pcm_get_format_name-static.patch [1]
    - 0002-asound.h-include-time.h-to-get-struct-timespec-proto.patch [2]

The Makefile has changed a lot, so we take advantage of that to simplify
our package.
