Assert when signing an ipa with .dSYM files inside

[ksagameng2]

I've noticed an issue when installing an ipa where multiple signers fail to sign it, eventually I tried using ldid directly and it was giving this error:

Upon further investigation it happens when it attempts to sign .dSYM files directly or more correctly when signing (binary name).dylib/Contents/Resources/DWARF/(binary name).dylib
It seems like it thinks that .dylib inside the dSYM should be signed

We can probably add a check in the recursive signing code to check against the debug symbols magic number and skip those files.

Can you send me an ipa with the dSYM that I can test with?

Please test pr #47 and see if it fixes the issue.

Please test pr #47 and see if it fixes the issue.

Seems to work correctly when signing the .app
