GetPrerequisites: Update output matching for newer 'file' versions
Detect PIE binaries with newer 'file' (5.22). It no longer prints
"(uses shared libraries)" but does print "interpreter":
# file 5.19
$ file /usr/bin/su
/usr/bin/su: ... shared object, ..., dynamically linked (uses shared libs), ...
# file 5.22
$ file /usr/bin/su
/usr/bin/su: ... shared object, ..., dynamically linked, interpreter /lib64/ld-linux-x86-64.so.2, ...
