Fix libc.dll not found exception causing breakpoints not to be bound

Not finding libc.dll causes an exception to fire and for us not to fall back to the Path.GetFullPath method.

This fixes it.
System.DllNotFoundException
HResult=0x80131524
Message=Unable to load DLL 'libc': The specified module could not be found. (Exception from HRESULT: 0x8007007E)
Source=Mono.Debugging
StackTrace:

at Mono.Debugging.Client.BreakpointStore.ResolveFullPath(String path) in D:\Repos\xamarinDebugVs\external\debugger-libs\Mono.Debugging\Mono.Debugging.Client\BreakpointStore.cs:line 489

This exception was originally thrown at this call stack:
Mono.Debugging.Client.BreakpointStore.ResolveFullPath(string) in BreakpointStore.cs
