Change "AutoReqProv: no" to "AutoReq: no"

Change "AutoReqProv: no" to "AutoReq: no"

This reverts commit 5529304523010614bcca9377fe50b9909bf3b548.

The "AutoReqProv: no" line disables automatic dependency generation
for both 'requires' and 'provides' rpm sections.
This caused errors for packages that used bcc-tools-devel, because
they required 'libbcc.so.0' but no package was providing it.

The line was probably added due to some kind of OBS issues with
dependencies, but the exact reason is unknown. We are going to
keep "AutoReq: no" so as not to bring these issues back. Maybe
a different approach via filtering dependencies could be tried
if this turns out insufficient.
