Fix gcc8 warnings.
Attempting to compile pacman with gcc8 results in several warnings like: remove.c: In function ‘unlink_file.isra.4’: remove.c:407:34: warning: ‘.pacsave.’ directive output may be truncated writing 9 bytes into a region of size between 1 and 4096 [-Wformat-truncation=] Fix by adding checks to error out if snprintf tries to reserve a truncated filename. Because the return values are checked, gcc delegates the truncation response to our code instead of throwing warnings.
