[git commit 0_9_30] sh/user.h: clean up conflicts from kernel user.h

[Andrew Stubbs]

commit: http://git.uclibc.org/uClibc/commit/?id=c3b9093409d9d7eade3ccefa6b61cac5985cb8af
branch: http://git.uclibc.org/uClibc/commit/?id=refs/heads/0_9_30

This patch makes sufficient modifications to the SH sys/user.h to be
able to build and run gdbserver with Linux kernel 2.6.30.

The problem is that both the kernel and library headers define the same
symbols, thus making it impossible in include both headers. The patch
undefines the kernel symbols in favour of the library symbols.
