Target remote mode fork and exec test updates

This patch updates tests for fork and exec events in target remote mode.
In the majority of cases this was a simple matter of removing some code
that disabled the test for target remote.  In a few cases the test needed
to be disabled; in those cases the gdb_protocol was checked instead of
using the [is_remote target] etc.

In a couple of cases we needed to use clean_restart, since target remote
doesn't support the run command, and in one case we had to modify an expect
expression to allow for a "multiprocess-style" ptid.

Tested with the patch that implemented target remote mode fork and exec
event support.

gdb/testsuite/ChangeLog:

	* gdb.base/execl-update-breakpoints.exp (main): Enable for target
	remote.
	* gdb.base/foll-exec-mode.exp (main): Disable for target remote.
	* gdb.base/foll-exec.exp (main): Enable for target remote.
	* gdb.base/foll-fork.exp (main): Likewise.
	* gdb.base/foll-vfork.exp (main): Likewise.
	* gdb.base/multi-forks.exp (main): Likewise, and use clean_restart.
	(proc continue_to_exit_bp_loc): Use clean_restart.
	* gdb.base/pie-execl.exp (main): Disable for target remote.

	* gdb.threads/fork-thread-pending.exp (main): Enable for target
	remote.
	* gdb.threads/linux-dp.exp (check_philosopher_stack): Allow
