pillow: drop the pybind11 build dependency

Pillow uses pybind11 only for pybind11.setup_helpers.ParallelCompile,
which parallelises the C extension build; it ships no runtime bindings.
Patch setup.py to remove that import and call and drop pybind11 from
build-system.requires, then remove python-pybind11/host from
PKG_BUILD_DEPENDS. The C extensions are compiled serially instead, with
no functional change to the package.

+Subject: [PATCH] setup.py: drop the pybind11 build dependency
+
+pybind11 is only used for pybind11.setup_helpers.ParallelCompile, a
+build-time helper that parallelises the C extension compilation. Pillow
+ships no pybind11 bindings, so remove the import, the ParallelCompile
+call and the pybind11 build-system requirement; the C extensions are
+then compiled serially.
