[PATCH 13/14] Revert "selftests: vDSO: parse_vdso: Use UAPI headers instead of libc headers"

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

This reverts commit c9fbaa879508 ("selftests: vDSO: parse_vdso: Use UAPI headers instead of libc headers")

The kernel headers were used to make parse_vdso.c compatible with nolibc.
Unfortunately linux/elf.h is incompatible with glibc's sys/auxv.h.
When using glibc it is therefore not possible build parse_vdso.c as part of the
same compilation unit as its caller as sys/auxv.h is needed for getauxval().

In the meantime nolibc gained its own elf.h, providing compatibility with the
documented libc interfaces.
