fix: Hotfix for py_binary

[nettle]

Why:
The actions executed a per target symlink to the script py_binary,
and the stub looks for its runfiles next to argv[0],
which fails on a remote worker.
The quoted analyze options collapse into a single argument.

What:

• Execute the script py_binary via files_to_run, drop the symlinks
• Pass the analyze options as --analyze=
• Always use plistlib load and dump, they exist since Python 3.4
