fix: remove broken patches = [...] lines from 2 recipes

`local/recipes/system/redbear-sessiond/recipe.toml`
referenced `../../../../local/patches/redbear-sessiond/
P4-signal-implementations.patch` which doesn't exist.
Removed the line — the recipe will fall back to
upstream-only behavior until the patch is created.

`local/recipes/wayland/libwayland/recipe.toml`
referenced `redox.patch` (relative path) which doesn't
exist. This was a re-add of the line that C-1
(commit 03c8a38a1) originally removed. The original
C-1 work identified that the libwayland redox.patch
file was missing and the `patches = [redox.patch]` line
was blocking the Wayland stack. The line got re-added
at some point, but the patch file is still missing.
Removed the line again to unblock the lint.
