vdso: Drop HAVE_GENERIC_VDSO from architecture kconfig files

Now that GENERIC_GETTIMEOFDAY and VDSO_GETRANDOM enable
HAVE_GENERIC_VDSO automatically, the architecture specific kconfig files
do not need to do so anymore.

Remove the corresponding lines.

Keep them for riscv, loongarch and powerpc as those have their own
explicit usage of the vDSO datastore provided by HAVE_GENERIC_VDSO.
