[PATCH] unstrip: Basename core module name when building -d output path

[Matej Smycka]

handle_output_dir_module builds each module's output file as
"OUTDIR/NAME".  For a core file NAME is the raw DT_SONAME reported by
libdwfl (dwfl_segment_report_module) with no basename applied, so a
DT_SONAME like "../../../path" makes eu-unstrip -a -m -d OUTDIR write
the reconstructed module image outside OUTDIR.  Basename the name when
joining it, as -m already implies and as link_map.c and core-file.c do.

	* src/unstrip.c (handle_output_dir_module): Use xbasename on the
	module name.
