d942f231af selftests/vDSO: Add riscv getcpu & gettimeofday test 
Enable vDSO getcpu & gettimeofday test for riscv. But only riscv64
supports __vdso_gettimeofday and riscv32 is under development.

cd76ca4dd6 selftests: vdso: Use a header file to prototype parse_vdso API 
Both vdso_test_gettimeofday and vdso_standalone_test_x86 use the library in
parse_vdso.c but each separately declares the API it offers which is not
ideal. Create a header file with prototypes of the functions and use it in
both the library and the tests to ensure that the same prototypes are used
throughout.

babf8a978d selftests: vdso: Rename vdso_test to vdso_test_gettimeofday 
Currently the vDSO kselftests have a test called vdso_test which tests
the vDSO implementation of gettimeofday(). In preparation for adding
tests for other vDSO functionality rename this test to reflect what's
going on.
