remove quotes around for loop elements

Right now kpatch-build fails when more than one object
file has changed because the quotes around the for loop
arrays cause the for loop to execute only once for all
elements in a single string.

Remove the quotes around the for loop arrays so that the
for loop is execute for each element.
