compare borg binaries produced by nuitka and pyinstaller

[ThomasWaldmann]

See #9721 (master branch) or scripts/build*.

Interesting would be (for both nuitka and pyinstaller):

• startup time for the single-file binary
• temporary space usage (e.g. /tmp)
• performance of a backup and a restore
• performance of borgfs filesystem (borg mount)

[ThomasWaldmann]

Also interesting:

• performance with CPython (pip install w/o using nuitka/pyinstaller)
• pypy performance (install/run using pypy w/o using nuitka/pyinstaller)

I can pick this up if it's ok?
