Fix support for the SIOCATMARK and SIOCGPGRP ioctls for xtensa by
correcting corresponding macro definition.

Values for TARGET_SIOCATMARK and TARGET_SIOCGPGRP are determined by
Linux kernel. Following relevant lines (obtained by grep) are from
the kernel source tree:

arch/ia64/include/uapi/asm/sockios.h:#define SIOCATMARK    0x8905
arch/mips/include/uapi/asm/sockios.h:#define SIOCATMARK    _IOR('s', 7, int)
arch/parisc/include/uapi/asm/sockios.h:#define SIOCATMARK  0x8905
arch/sh/include/uapi/asm/sockios.h:#define SIOCATMARK      _IOR('s', 7, int)
arch/xtensa/include/uapi/asm/sockios.h:#define SIOCATMARK  _IOR('s', 7, int)
arch/alpha/include/uapi/asm/sockios.h:#define SIOCATMARK   _IOR('s', 7, int)
arch/sparc/include/uapi/asm/sockios.h:#define SIOCATMARK   0x8905
include/uapi/asm-generic/sockios.h:#define SIOCATMARK      0x8905

arch/ia64/include/uapi/asm/sockios.h:#define SIOCGPGRP     0x8904
arch/mips/include/uapi/asm/sockios.h:#define SIOCGPGRP     _IOR('s', 9, pid_t)
arch/parisc/include/uapi/asm/sockios.h:#define SIOCGPGRP   0x8904
arch/sh/include/uapi/asm/sockios.h:#define SIOCGPGRP       _IOR('s', 9, pid_t)
arch/xtensa/include/uapi/asm/sockios.h:#define SIOCGPGRP   _IOR('s', 9, pid_t)
arch/alpha/include/uapi/asm/sockios.h:#define SIOCGPGRP    _IOR('s', 9, pid_t)
arch/sparc/include/uapi/asm/sockios.h:#define SIOCGPGRP    0x8904
include/uapi/asm-generic/sockios.h:#define SIOCGPGRP       0x8904

It is visible from above that xtensa should have the same definitions
as alpha, mips and sh4 already do. This patch brings QEMU to the accurate
state wrt these two ioctls.
