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, ...
