yum_install: fix awk return code

TIL:

  Similarly, all the END rules are merged, and executed when all the
  input is exhausted (or when an exit statement is executed).

i.e. matching YUM_FAILED calls "exit", which falls through to the END
rules which calls "exit result" ... which is zero.  i.e. if the return
code is 1 then we actually hide that and return with zero.

This is rather annoying because errors that should halt to alert us of
a package install failure pass through, only for you to have to debug
much later on seemingly unrelated problems.

This always sets "result" and thus should be returning the right
thing.  I've updated the documentation to hopefully make it clearer
what's going on.
