[PATCH 4.17 167/220] perf tools: Fix symbol and object code resolution for vdso32 and vdsox32

[Greg Kroah-Hartman]

4.17-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Adrian Hunter <adrian.hunter@xxxxxxxxx>

commit aef4feace285f27c8ed35830a5d575bec7f3e90a upstream.

Fix __kmod_path__parse() so that perf tools does not treat vdso32 and
vdsox32 as kernel modules and fail to find the object.
