fix: awk select correct column if some packages are installed

awk used `$2` to print the second _word_ of each line of `zypper search
texlive` output. If some packages are installed, the first column
contains `i` and the second _word_ will be `|`. If the field separator
is set to `-F '|'`, awk prints the second _column_ containing the
package name.
