process-debuginfo: Do not strip&split debugging vmlinux binary

crash is unable to handle vmlinux split into vmlinux.debug because it
cannot find `.symtab`[1]. This is not expected to be fixed soon.

Really, there is not point to split it because both halves are in
the same -debuginfo package and this is only complicates things.

This also undoes approach taken in 894f4140c ("process-debuginfo: Add
.gnu_debuglink symlink for vmlinux").
