python-installer: drop the flit-core constraint patch

The feed reverted python-flit-core to 3.12.0, which satisfies the
upstream "flit_core<4,>=3.11" build requirement, so the relaxation
patch is no longer needed.

-Subject: [PATCH] python-installer: allow flit_core 4.x as the build backend
-
-installer caps its flit_core build requirement below 4, so python-installer/host fails
-with "Missing dependencies: flit_core<4" now that the feed ships flit-core
-4.0.2. flit_core 4 builds it unchanged; relax the upper bound.
