[PATCH v2 06/16] elf, uapi: Add types ElfXX_Verdef and ElfXX_Veraux

["Thomas Weißschuh" <thomas.weissschuh@linutronix.de>]

The types are used by tools/testing/selftests/vDSO/parse_vdso.c.
To be able to build the vDSO selftests without a libc dependency,
add the types to the kernels own UAPI headers.
