This revision now requires changes to proceed.
I think doing this in the module list is not the right place. Why? Some
platforms might have multiple sysroot to check. iOS for instance has a
directory for each device that Xcode has connected to which can be checked. I
am fine with adding this ability to lldb_private::Platform, but I would just do
it in there. Try GetRemoteSharedModule with the spec, if it fails, try again
after modifying the spec to prepend the sysroot path. Possible even just check
the sysroot path + path first if m_sdk_sysroot is filled in. I don't see the
need to change ModuleList itself.

----------------
Here just make a module spec that has m_sdk_sysroot prepended if m_sdk_sysroot
is set, and check for that file first. If that succeeds, return that, else do
the same code as before.
