Fix warning linking static libraries on OS X 10.9

libtool on OS X 10.9 will output message such as:

/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/libtool: file: gen/third_party/libvpx/x86inc.o has no symbols

instead of

libtool: file: gen/third_party/libvpx/x86inc.o has no symbols

As a result, the pattern used by gyp-mac-tool to filter these
kind of messages (r'libtool: file: .* has no symbols$') no longer
works. Extend the pattern a little bit to support output with
full directory names.
