Subject: [PATCH] Fix buffer overflow in Backup.Creator

I noticed that while testing the upcoming GCC 12 with -D_FORTIFY_SOURCE=3:
here I have

$1 = 0x7ffff7f0f940 <Buffer.1.lto_priv.1> "Linux, kernel 5.16.14-1-default (#1 SMP PREEMPT Fri Mar 11 12:33:34 UTC 2022 (80acc65))"
(gdb) p (int)strlen(GetOS())
$3 = 87
so GetOS() returns 87 chars while:

include/gammu-backup.h: char Creator[80];

Fixes: #701
