Revert "selftests: vDSO: parse_vdso: Use UAPI headers instead of libc headers"

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.
