fix(security): path traversals

[jacobprezant]

Description

Fixes several path traversals that give arbitrary read/write to an attacker when handling a crafted .ipa, or in some cases a hostile iPhone. For example, during patching, a malicious .ipa could copy any file into its packed archive due to the use of CFBundleExecutable from the archive's Info.plist without proper sanitization in building paths.
