pkg/csource: compile single pseudo syscalls

There seem to be a lot of unclear dependencies between pseudo syscall
code and global methods. By testing them only together we have little
chance to detect these problems because implementations can indiretly
help one another.

In addition to existing tests, also compile all pseudo syscalls
independently.
