Fixed coverage on OSX (dependency on pipe2)

Removed use of 'realpath' in makefiles to fix OSX incompatibility
Fixed handling of when prefetching should be enabled
Snap the main binary during initialization to avoid stability issues with lazy loading
Add support for configurable inline cache entries for FRIDA on x86/x64
