char prefix[13 + 1 + 20 + 6 + 1];
/var/run/user -> 13
/ -> 1
UID -> 20 (for a 64 bit unsigned integer)
/gnupg -> 6
nul -> 1
and indeed I did not add 6 extra bytes for the leading "/gnupg".
However, it is not a problem: A 32 bit user id (e.g. 2147483647) does
only need 10 bytes and thus there is enough space for the extra string.
If the ID would really grow to a larger 64 bit value, this will not
work anymore and the explict check will let it return an error.
Although I tested this I obviously did not noticed that we will end up
with a socket directory
The second gnupg would not be needed. The question is whether to remove
it or to keep it for code simplicity. I will fix the size of the
