selftests: vDSO: vdso_standalone_test_x86: Replace source file with symlink
With the switch over to nolibc the source file vdso_standalone_test_x86.c
was intended to be replaced with a symlink to vdso_test_gettimeofday.c.
This was the patch that was submitted to LKML, but during application the
symlink was replaced by a textual copy of the linked-to file.
Having two copies introduces the possibility of divergence and increases
maintenance burden, switch back to a symlink.

According to limits.h(2) ULONG_MAX is only guaranteed to expand to an
expression, not a symbolic constant which can be evaluated by the
preprocessor.
Specifically the definition of ULONG_MAX from nolibc can not be evaluated
by the preprocessor. To provide compatibility with nolibc, check with
__SIZEOF_LONG__ instead, with is provided directly by the preprocessor
and therefore always a symbolic constant.

selftests: vDSO: unconditionally build getrandom test
Rather than building on supported archs, build on all archs, and then
use the presence of the symbol in the vDSO to either skip the test or
move forward with it.
Note that this means that this test no longer checks whether the symbol
was correctly added to the kernel. But hopefully this will be clear
enough to developers and we'll cross our fingers that symbols aren't
removed by accident and not caught after this change.
