www/node: Update 12.7.0 -> 12.8.0
https://nodejs.org/en/blog/release/v12.8.0/
The bundled OpenSSL configuration now includes BSD-x86, which this port
can now use. The build for i386 is still using the no-asm variant for
the time being. Assembler errors in BSD-x86/asm-avx2 need to be
investigated to be able to enable asm with the bundled OpenSSL.
While here, regenerate all remaining patches with make makepatch.
