Tiny fixes to recent native compilation docs

For discussion, see the following thread:
https://lists.gnu.org/r/emacs-devel/2021-05/msg00347.html

* doc/lispref/compile.texi (Native Compilation): Fix grammar in @ref
online label.
(Native-Compilation Functions): Consistently unhyphenate
'sub-process'.  Fix grammar.
(Native-Compilation Variables): Fix @cindex entry.
