gdb/testsuite: remove gdb.python/pretty-print-call-by-hand.exp
This test was added without a corresponding fix, with some setup_kfails. However, it results in UNRESOLVED results when GDB is built with ASan. ERROR: GDB process no longer exists GDB process exited with wait status 1946871 exp7 0 1 UNRESOLVED: gdb.python/pretty-print-call-by-hand.exp: frame print: backtrace test (PRMS gdb/28856) Remove the test from the tree, I'll attach it to the Bugzilla bug instead [1].
