bug#68948: highlight error, cannot open filetypes.conf: No such file or directory

[chris]

Sergey,

I believe you intended a related message for the debbugs service, but only sent 
the message to my mail address. I am unsure and want to avoid showing 
impoliteness, I rephrased your message a bit below. Thank you,

Chris

-------------------

the highlight error goes away after copying the conf file this way
```
cp $(guix build highlight)/etc/highlight/filetypes.conf ~/.highlight/
```

strace shows that the conf is searched in wrong place:

--8<---------------cut here---------------start------------->8---
newfstatat(AT_FDCWD, "/home/user/.highlight/filetypes.conf", 0x7ffcd0778130,
0) = -1 ENOENT (No such file or directory)
newfstatat(AT_FDCWD, 
"/gnu/store/9mdd4ba8ri4j07acmbc2vhkiipbz9l63-highlight-4.8/share/highlight/filetypes.conf",
0x7ffcd0778130, 0) = -1 ENOENT (No such file or directory)
newfstatat(AT_FDCWD, 
"/gnu/store/9mdd4ba8ri4j07acmbc2vhkiipbz9l63-highlight-4.8/share/highlight/config/highlight/filetypes.conf",
0x7ffcd0778130, 0) = -1 ENOENT (No such file or directory)
openat(AT_FDCWD, "filetypes.conf", O_RDONLY) = -1 ENOENT (No such file or
directory)
futex(0x7f2c4827e1f0, FUTEX_WAKE_PRIVATE, 2147483647) = 0
write(2, "cannot open filetypes.conf: No s"..., 53cannot open
filetypes.conf: No such file or directory) = 53
--8<---------------cut here---------------end--------------->8---

but it is installed to
/gnu/store/...-highlight-.../etc/highlight/highlight.conf
the package recipe has to be fixed
