Add more POSIX compliance macros to fix uClibc support

- Add POSIX 1993.09 compliance macro in source files that use
  "struct timespec";
- Add POSIX 2001.12 compliance macro in source files that use
  "struct sigaction" and the SA_SIGINFO macro, or the fchmod()
  function;
- Add POSIX 2008.09 compliance macro in source files that use the
  getline() function.

These compliance macros are enough for wlroots to compile with the
git-master version of uClibc-ng.
