make dprintf.exp pass in target async mode
When target-async is enabled, dprintf.exp fails:

(gdb) FAIL: gdb.base/dprintf.exp: 1st dprintf, call
The problem is that GDB gave the prompt back to the user too early.
This happens when calling functions while handling an event that
doesn't cause a user visible stop. dprintf with "set dprintf-style
gdb" is one such case. This patch adds a test case that has a
breakpoint with a condition that calls a function that returns false,
so that regression testing isn't dependent on the implementation of
dprintf.
The problem happens because run_inferior_call causes GDB to forget
that it is running in sync_execution mode, so any event that runs an
inferior call causes fetch_inferior_event to display the prompt, even
if the event should not result in a user visible stop (that is, gdb
resumes the inferior and waits for the next event).
This patch fixes the issue by noticing when GDB was in sync_execution
mode in run_inferior_call, and taking care to restore this state
afterward.
