UML - stop using libc asm/user.h

commit 189872f968def833727b6bfef83ebd7440c538e6 in mainline.

uml: don't use glibc asm/user.h

Stop including asm/user.h from libc - it seems to be disappearing from
distros.  It's replaced with sys/user.h which defines user_fpregs_struct and
user_fpxregs_struct instead of user_i387_struct and struct user_fxsr_struct on
i386.

As a bonus, on x86_64, I get to dump some stupid typedefs which were needed in
order to get asm/user.h to compile.
