Restore tcb::u_lrval; fix lseek on MIPS-n32
Linux kernel v3.4 adds x32 support. Both x32 and n32 use 64bit offset
for lseek parameter and return value. We need u_lrval to handle it
properly. Also we shouldn't check HAVE_LONG_LONG_OFF_T for n32 lseek.
This patch fixes it properly and prepares lseek for x32.
* defs.h (tcb): Restore tcb::u_lrval field, RVAL_Lfoo constants.
Set RVAL_MASK to 7.
* file.c (sys_lseek): Print 64bit offset and return RVAL_LUDECIMAL
for n32.
* syscall.c (get_error): Set u_lrval for MIPS-n32.
(trace_syscall_exiting): Handle RVAL_Lfoo return value types.
