Simon Marchi bea3329b76 gdb: check result of gdb_fopen_cloexec in dump_binary_file 
Bug 27773 shows that passing a filename in a non-existent directory to
the "dump binary" command leads to a gdb crash.  This is because the
gdb_fopen_cloexec in dump_binary_file fails (returns nullptr) and the
return value is not checked.  Fix that by erroring out if
gdb_fopen_cloexec fails.

gdb/ChangeLog:

	PR gdb/27773
	* cli/cli-dump.c (dump_binary_file): Check result of
	gdb_fopen_cloexec.

gdb/testsuite/ChangeLog:

	PR gdb/27773
	* gdb.base/dump.exp: Test dump to non-existent dir.
