linux-user: Translate getsockopt level option

Browse Source 
n setsockopt, the socket level options are translated to the hosts'
architecture before the real syscall is called, e.g.
TARGET_SO_TYPE -> SO_TYPE. This patch does the same with getsockopt.

Tested on a x86 host emulating MIPS.  Without it:-

$ grep getsockopt host.strace
31311 getsockopt(3, SOL_SOCKET, 0x1007 /* SO_??? */, 0xbff17208,
0xbff17204) = -1 ENOPROTOOPT (Protocol not available)

With:-

$ grep getsockopt host.strace
25706 getsockopt(3, SOL_SOCKET, SO_ERROR, [0], [4]) = 0
