toolchain: use consistent code style for C code

Most, but not all our C code follows the Linux kernel code style (as
documented in Documentation/process/coding-style.rst).  Adjust the few
places doing differently:

- Braces:
  ..but the preferred way, as shown to us by the prophets Kernighan
  and Ritchie, is to put the opening brace last on the line

- Spaces after keywords:
  Use a space after (most) keywords
