semihosting: Split out semihost_sys_lseek
Split out the non-ARM specific portions of SYS_SEEK to a reusable function. This handles all GuestFD. Isolate the curious ARM-specific return value processing to a new callback, common_semi_seek_cb. Expand the internal type of the offset to int64_t, and provide the whence argument, which will be required by m68k and nios2 semihosting. Note that gdb_do_syscall %x reads target_ulong, not int.
