[gdb/testsuite] Fix gdb.btrace/tsx.exp on system with tsx disabled in microcode
Recently I started to see this fail with trunk:
...
(gdb) record instruction-history^M
1 0x00000000004004ab <main+4>: call 0x4004b7 <test>^M
2 0x00000000004004c6 <test+15>: mov $0x1,%eax^M
3 0x00000000004004cb <test+20>: ret ^M
(gdb) FAIL: gdb.btrace/tsx.exp: speculation indication
...
This is due to an intel microcode update (1) that disables Intel TSX by default.
Fix this by updating the pattern.
Tested on x86_64-linux, with both gcc 7.5.0 and clang 12.0.1.
