Log message:
python/wheel.mk: simplify a lot, and switch to 'installer' for installation

This follows the recommended bootstrap method (flit_core, build, installer).

However, installer installs different files than pip, so update PLISTs
for all packages using wheel.mk and bump their PKGREVISIONs.

read_bytes(): use previous implementation again for small reads
      For small reads, the new code that tries to avoid unnecessary reads is
noticeably slower than the previous code that reads unconditionally. In
the worst case (1-byte reads), the new code is 13 times as slow as the
previous implementation. The potential memory/IO savings only become
worth it for larger reads, where the performance difference disappears.

Log message:
*: bump PKGREVISION for egg.mk users

They now have a tool dependency on py-setuptools instead of a DEPENDS
