linux-user: Fix stat64 syscall for SPARC64

Some targets use a stat64 structure for the stat64 syscall while others
use a stat structure. SPARC64 used the wrong kind.

Instead of extending the conditional compilation in syscall.c, now a
macro TARGET_HAS_STRUCT_STAT64 is defined whenever a target has a
target_stat64.
