Subject: [PATCH] Rmove ELF magic for application/x-sharedlib, generalize
 x-executable magic.

PIE executables have the same header as ELF shared libs and therefore
were being detected as shared libraries.

The magic for executables was too specific, I removed the check
for the value at offset 16 since it's actually 3 for /usr/bin/ls, not 2.

Fixes gitlab issue #11.
