remove external __syscall function and last remaining users
the weak version of __syscall_cp_c was using a tail call to __syscall to avoid duplicating the 6-argument syscall code inline in small static-linked programs, but now that __syscall no longer exists, the inline expansion is no longer duplication. the syscall.h machinery suppported up to 7 syscall arguments, only via an external __syscall function, but we presently have no syscall call points that actually make use of that many, and the kernel only defines 7-argument calling conventions for arm, powerpc (32-bit), and sh. if it turns out we need them in the future, they can easily be added.
