merge multiple *fetch version functions into one

[adamperkowski]

these functions:

fetchfetch/stats.c

Lines 82 to 92 in f684db4

	char* fastfetch() {
	// NOTE Version in the format "fastfetch x.x.x (ARCH)"
	char *out = app_version("fastfetch --version");
	return extract_named_version(out, "fastfetch ");
	}
	char* neofetch() {
	// NOTE Version in the format "Neofetch x.x.x"
	char *out = app_version("neofetch --version");
	return extract_named_version(out, "Neofetch ");
	}

could be merged into one. like this:

FetchStat* get_stats() {
	FetchStat *stats = malloc(STATS_SIZE * sizeof(FetchStat));
	stats[0].label = "Fastfetch";
	stats[0].version = get_version(/* command */ "fastfetch --version", /* prefix */ "fastfetch ");
	return stats;
}

You're right. I'm perhaps overthinking things, but this was intentional redundancy to make things a little easier if a single *fetch tool needs special handling in the future. That way only FETCHER() would have to be modified, and not get_stats().
