pyroscope-io: add the riscv64 py-spy patches for 1.3.0 and 1.4.0

Each version pins a different py-spy revision (ad722cc, 44736d9) and has
no [features] section left in rust/Cargo.toml, so the Cargo patch is
rebased per version; the py-spy patch applies unchanged at both.

+Subject: [PATCH] cargo: build py-spy from a locally patched checkout
+
+py-spy does not compile for riscv64: pyruntime::get_tstate_current_offset
+is defined once per architecture and riscv64 matches none of the arms, so
+the build fails with
+
+    error[E0425]: cannot find function `get_tstate_current_offset` in module `pyruntime`
+
+py-spy is pulled in as a git dependency pinned to a revision, so the fix
+cannot be applied in place. Redirect the git source to a checkout of that
+same revision carrying the one-line riscv64 addition, see
+0002-python_bindings-return-no-tstate_current-offset-on-riscv64.patch.
+
+Only the source line of the py-spy entry changes in Cargo.lock, so every
+other dependency stays pinned exactly as upstream released it and the
+build keeps running with --locked.
+
+Upstream-Status: Inappropriate [redirects a pinned dependency to a local checkout; the fix itself belongs in py-spy]

+Applied to the py-spy checkout that pyroscope-python pins as a git

+pyruntime::get_tstate_current_offset has one definition per architecture

+Add riscv64 to the arm that returns None, the same answer powerpc, powerpc64

+the caller already handles None by reporting an unknown offset; 3.12 and
+later read the GIL through a struct offset instead.
