We already had implementations of some of the functions, and I didn't
bother rewriting them when we added sysinfo(2). Ross Anderson said in
https://www.lightbluetouchpaper.org/2016/07/29/yet-another-android-side-channel/
that we should "simply disable access to all procfs files", which made
me curious how many places we use /proc in bionic. This is the one that's
obviously unnecessary. The others I'm not aware of alternative APIs for.

open(2) can be used to open directories; use stat to
check that the file exists and is a regular file.

Hiding our legacy cruft seemed like a good idea, but in practice it will only
mean worse interoperability.
Plus we got it wrong, as the recent `putw` example showed.

separate files.

code that belongs to libdl.so and remove parts of
the code that do not belong to linker
(refactoring part 2 of many)
