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.
