When using software collections, rpmbuild doesn't put debuginfo information in the correct location in RHEL 6.

Issue

• When building a package into a collection it installs the files in the pseudo root for the collection (ie. /opt/rh/<collection>/root). However, when creating the debuginfo RPM, the files get installed into the system's normal location of /usr/src/debug instead of /opt/rh/<collection>/root/usr/src/debug.
