This saves about 2 MiB from the package. When all rpms get extracted,
the comparison is as follows on an ext4 filesystem:
With this patch:
$ du -s usr
195828 usr/
Without this patch:
$ du -s usr
198224 usr/
Which is a difference of 2.396 MiB.
To reduce the filesystem footprint of the Python installation, some
files are now being removed and only one level of their pycache
(non-optimized) is being kept.
These particular files were chosen for their size and the fact that they
are autogenerated, thus hard to read.
