[PATCH] Use correct dylib ID in Darwin loadable modules

[Lawrence Velázquez]

Even though loadable modules are not named using the shared-library
prefix (e.g., "lib"), their dylib IDs currently contain the prefix
anyway. Thus "LLVMPolly.dylib" is installed with an ID of
"@rpath/libLLVMPolly.dylib". After this change, its ID would be
"@rpath/LLVMPolly.dylib", as expected.
