[gdb/tdep] Handle sycall statx for arm-linux

When running test-case gdb.reverse/fstatat-reverse.exp on arm-linux, I run
into:
...
(gdb) continue^M
Continuing.^M
Process record and replay target doesn't support syscall number 397^M
Process record does not support instruction 0xdf00 at address 0xf7ebf774.^M
Process record: failed to record execution log.^M
^M
Program stopped.^M
0xf7ebf774 in ?? () from /lib/arm-linux-gnueabihf/libc.so.6^M
(gdb) FAIL: gdb.reverse/fstatat-reverse.exp: continue to breakpoint: marker2
...

Syscall number 397 stands for statx on arm-linux.

Fix this by handling 397 in arm_canonicalize_syscall.

Tested on arm-linux.
