Fix uniqueness check of initrd in fedora-minimal

Browse Source 
The check suffered from various flaws.

First, due to missing quotes around $initrd, 'wc -l' would always see
1 line no matter how many results the find returned.

Second, echo adds a line break making 'wc -l' count 1 even for empty
string. We need to add a check for empty string.
