procps: fix two small problems

1. Fix HOMEPAGE. The old one is obsolete.

2. Remove the setting of CPPFLAGS.
It was used to support out-of-tree build. But the problem has been
fixed upstream since commit 90cc5460aa0e9ca10a0d7c8c44064fd14789f750
(build-sys: add $(top_srcdir) to include search dir).
