vendor/bc: import of version 5.3.1

This update does not contain any functional change, but fixes two
minor build issues:

- Temporary files were created in the source directory, causing build
  failures if the sources were not writable at build time.
- A message catalogue contained extra characters that were ignored but
  made gencat print warning messages.
