Removing rpmrc from rpm-4_5

[Jeff Johnson]

From conversations with several, the rpm-4_5 branch seems to
be mostly willing to live without reading /usr/lib/rpm/rpmrc by default.

No matter what, rpm-5.0 is not going to read rpmrc files ever again.

If there is a need to read rpmrc for some interpretation of
   "everywhere compatible"
then not only the first argument to rpmReadConfigFiles() needs to be  
changed.

In addition, there will be some modest number of macro values that  
will need to
be initialized so that Good Old Paths expand correctly. Not hard at  
all to add,
in fact is exactly as hard as identifying what path macros need to be  
initialized.

IIRC, Mark added 3 paths in order to install rpm-4.5 path  
independently. Note
that rpm-4_5 is likley going to install in /usr/bin, not /bin, so  
that the relocation
rules are simpler. Good, renaming to /bin/rpm5 would have driven me  
nuts.

Here's an example of the type of failure to expect if you are trying  
to preserve
reading /usr/lib/rpm/rpmrc by default.

This error is from yum before I turned off /usr/lib/rpm/rpmrc:

# yum upgrade

or directory.
