use dist-hook instead of listing directories in EXTRA_DIST

Hi,

New dist file with generated documentation (-dist) and configure script is now over 6Mbyte in size (1.47.0) which is quite a jump from 1.46.0. Switching to xz/lzma would cut this is in more than half, downside is that it takes slightly longer to generate but given it's a small library I think that's worth the tradeoff.

I fixed the current files and re-released those.

It seems the trouble is the way we use EXTRA_DIST
https://www.gnu.org/software/automake/manual/html_node/Basics-of-Distribution.html

libuv/Makefile.am

Lines 121 to 131 in 815693f

	EXTRA_DIST = test/fixtures/empty_file \
	test/fixtures/load_error.node \
	test/fixtures/lorem_ipsum.txt \
	test/fixtures/one_file/one_file \
	include \
	docs \
	img \
	CONTRIBUTING.md \
	LICENSE \
	LICENSE-extra \
	README.md

I am not sure of a good way around that, since we cannot use git ls-tree in the dist tree (the git files are not copied) and we cannot even use $(wildcard) or find since automake will error with a warning it is non-portable.

Thanks!
