firetools can't create `~/.config/firetools` if `~/.config` doesn't exist

The code here:

firetools/src/common/utils.cpp

Lines 139 to 156 in 81ca775

	// create firetools directory if it doesn't exist
	void create_config_directory() {
	struct stat s;
	char *path;
	char *homedir = get_home_directory();
	if (asprintf(&path, "%s/.config/firetools", homedir) == -1)
	errExit("asprintf");
	free(homedir);
	if (stat(path, &s) == -1) {
	/* coverity[toctou] */
	int rv = mkdir(path, 0755);
	if (rv == -1) {
	fprintf(stderr, "Error: cannot create %s directory\n", path);
	exit(1);
	}
	}
	free(path);
	}

can't create the ~/.config/firetools directory if ~/.configdoesn't exist. Apparently mkdir(...) doesn't directly support creating all the directories along the path (the way mkdir -p does).

This makes firetools fail to launch if ~/.configdoesn't exist.

Specifically, while this may be a rare occurrence in regular users' home directories, it can happen when launching firetools as root (having the home directory /root) where the home directory may not contain a .config subdirectory by default in some distributions.
