lxc: restore DEBUG_PREFIX_MAP in TARGET_LDFLAGS for LTO reproducibility
oe-core [1] removed DEBUG_PREFIX_MAP from TARGET_LDFLAGS to avoid passing
prefix-map options via the linker flags. This is fine for most projects
since DEBUG_PREFIX_MAP is also provided via CFLAGS at configure time.
However, lxc enables LTO by default, which causes link-time code generation
to (re)emit debug information during the link step. Without DEBUG_PREFIX_MAP
on the link command line, TMPDIR/WORKDIR paths can leak into DWARF,
triggering the buildpaths QA check and breaking reproducibility.
Append DEBUG_PREFIX_MAP back to TARGET_LDFLAGS for lxc to ensure prefix-map
options are visible during LTO link-time compilation.
