[bug#32095] [PATCH 1/2] gnu: libuv: Update to 1.21.0.

Actually this upgrade is not OK as is for ‘master’ because (1) 2,9K
packages depend on libuv via CMake, and (2) the upgrade breaks CMake
like this:

I think one way around it, as a first step, is to define libuv-1.21
separately, for use by Node.

Could you try that?

Thanks in advance,
Ludo’.
