RISC-V: Update AT_VECTOR_SIZE_ARCH for new AT_MINSIGSTKSZ

"riscv: signal: Report signal frame size to userspace via auxv" (e92f469)
has added new constant AT_MINSIGSTKSZ but failed to increment the size of
auxv, keeping AT_VECTOR_SIZE_ARCH at 9.
This fix correctly increments AT_VECTOR_SIZE_ARCH to 10, following the
approach in the commit 94b07c1 ("arm64: signal: Report signal frame size
to userspace via auxv").
