Building on arch

I was able to build & install without any issues
But I had to change this 

```
git diff
diff --git a/Makefile b/Makefile
index c231153..0b29021 100644
--- a/Makefile
+++ b/Makefile

-USBMUXD      ?= libusbmuxd
+USBMUXD      ?= libusbmuxd-2.0
 
-SRC += /opt/libimobiledevice/lib/libusbmuxd.a
+SRC += /opt/libimobiledevice/lib/libusbmuxd-2.0.a
```
