Fixing some pytest tests that were failing on my local machine or the CI I'm working on.

  • DEVELOPER=0 + VALGRIND=1 + an expected node failure don't combine that well, since the backtrace can't find debug symbols
  • The TOR tests didn't really format their options correctly, this remained undiscovered since apparently no dev is running TOR locally, except me ;-)
  • hsmtool was assuming the $cwd is on the same partition as the lightning-dir.

Valgrind doesn't really like crashes if compiled without DEVELOPER since that
seems to compile out the debug symbols, resulting in the following error:

```
Optimistic lock on the database failed. There may be a concurrent access to the database. Aborting since concurrent access is unsafe.

TIL: `rename` doesn't like its source and target to be on different
partitions. This was causing the `hsmtool` tests to fail whenever we ran them
on a different partition than the lightning-dir (e.g., `/dev/shm` for faster
testing), because we made the backup copy in the current working directory.

This changes this and creates the backup next to the original file, which has
a reasonable chance to be on the same partition.

Changelog-Changed: hsmtool: The `hsmtool` now creates its backup copy in the same directory as the original `hsm_secret` file.
