[PATCH 1/1] rootfs: do not clean pycache for distros that build it reproducible

['Felix Moessbauer' via isar-users]

The reproducible builds issues in the pycache have finally been solved
and the corresponding fixes are available from bookworm on.
By that, we no longer drop the pycache for distros that build it
reproducibly, as this speeds up first-time invocations of python tools
in the rootfs. This is especially relevant in cases where the pycache
cannot be written at all, e.g. because the rootfs is read only mounted.
