Re-enable statvfs() tests now that -CURRENT has the function.

Improve build reliability:
* Make very sure that the build script is run with /bin/sh.
* Add a dubious patch to libast/comp/conf.sh that is reported to fix
  the build for some -STABLE users.

Install example functions.

-CURRENT has <sys/statvfs.h> but no actual statvfs() implementation,
which badly confuses the configure tests that check for this
functionality.  Remove the tests for the time being.
