linux-user: avoid using glibc internals in _syscall5 and in definition of target_sigevent struct
Use the public sigset_t instead of the glibc specific internal
__sigset_t in _syscall.
Calculate the sigevent pad size is calculated in similar way as kernel
does it instead of using glibc internal field _pad.
This is needed for building with musl libc.
