DEFFILEMODE is not defined on musl libc.
Linus has expressed preference towards using explicit octal value in
the past over combinaisons of S_Ix{USR,GRP,OTH}, so just replace it
with 0666 directly

I wanted to link to the Linus mail that said this, but it turns out
there weren't any list in Cc... I could be making this up but here's the
relevant part of his mail, which I hope is acceptable to forward as
there's nothing personal in it:

Finally, I absolutely _abhor_ the crazy "S_%&^%&^$" macros. They are
completely illegible garbage, imnsho. I'm looking at that
+ mode = stat->st_mode & S_IALLUGO;
+ mode |= inode->i_mode & ~S_IALLUGO;
and I'm like "WTF is that random character sequence again".
In this case, it's everything but the format. I think it would be
more legible written the other way around, ie
+ mode = stat->st_mode & ~S_IFMT;
+ mode |= inode->i_mode & S_IFMT;
because at least that one has _less_ of the stupid random-generated letters.
Every single one of the "UGO" things are pure and utter crap. The
octal representation of the actual permissions masks are _way_ more
legible than the insane "standard" names for them.
