[gdb/testsuite] Exit left-over gdb in gdb.mi/mi-break.exp
After test-case gdb.mi/mi-break.exp, a gdb instance is left running.
The test-case starts two instances using mi_clean_restart, one using
separate-mi-tty.
For each instance, gdb_exit is called once, from two different locations:
- mi_clean_restart, and
- gdb_finish.
But this doesn't seem to be effective for the separate-mi-tty case.
Fix this by calling gdb_mi_exit at the end of proc test_break.
Likewise in a few more more test-case.
Tested on x86_64-linux.
