py3: fix broken man page generation, it was generating `(default: NUL*)`
`bytes(default)` was producing things like `(default: \x00)` when handed
non-bytes values such as `1`, `10`, or `True`. The man page generation would
apparently ignore these bytes and produce man pages that had the string
`(default: )`.
Test Plan:
- Ran `cd doc; python3 gendoc.py "hg.1.gendoc"` and grepped for bad output
- Ran `make deb`, extracted the deb, manually inspected `hg.1` file.
