btrace, testsuite: fix spurious gdb.btrace/tsx.exp fails 

If the atomic section in x86-tsx.S is aborted, the tsx.exp test will fail
even if the traced output is actually correct.

Consider abort scenarios in the test.

testsuite/
	* gdb.btrace/tsx.exp: Consider multiple correct outputs in the record
	instruction-history test.
