[PATCH 5.17 008/772] riscv: Wire up memfd_secret in UAPI header

From: Tobias Klauser <tklauser@distanz.ch>

commit 02d88b40cb2e9614e0117c3385afdce878f0d377 upstream.

Move the __ARCH_WANT_MEMFD_SECRET define added in commit 7bb7f2ac24a0
("arch, mm: wire up memfd_secret system call where relevant") to
<uapi/asm/unistd.h> so __NR_memfd_secret is defined when including
<unistd.h> in userspace.

This allows the memfd_secret selftest to pass on riscv.
