This commit fixes wrap-find-debuginfo.sh so that:
* the .gnu_debuglink section of libc.so.6 is retained, and
* the redundant debuginfo file generated for ld.so is removed

Apparently, debugedit changes the build ID, so the separated debuginfo
no longer matches the specially crafted copy of libc.so.6 with its
minimal .symtab.
This adds patches proposed upstream to enable downgrades across
major glibc versions.
File list construction and the find-debuginfo.sh wrapper had
to be adjusted to cope with the changed file name patterns.
This needs a wrapper script around find-debuginfo.sh, so that
ld.so is not stripped.
This commit resolves debuginfo file conflicts (#1886295) because
the ldconfig debuginfo file now includes the architecture name.
All debugging information is preserved in ld.so (#1905611). With
the distribution defaults, we strip all binaries again (#1661510).
