fbterm: fix musl compile

- add missing include, fixes:

  fbio.cpp:33:8: error: ‘fd_set’ does not name a type
   static fd_set fds;

  improxy.cpp:439:3: error: ‘fd_set’ was not declared in this scope

- add missing WAIT_ANY define, fixes:

  fbterm.cpp: In member function ‘void FbTerm::processSignal(u32)’:
  fbterm.cpp:212:22: error: ‘WAIT_ANY’ was not declared in this scope
      s32 pid = waitpid(WAIT_ANY, 0, WNOHANG);
