deps: upgrade to libuv 1.30.1 #28511
This upgrade is a small patch release, fixing compilation errors on Android, Cygwin, and uClibc - none of which are tested in the CI.
I'd like to propose fast tracking this so that it can make it into the 12.6.0 release. It has already been run in the CI (as all libuv releases are these days), and is a very small release that fixes issues on untested platforms. cc: @nodejs/libuv
EDIT(cjihrig): CI was yellow.
