Adapt to cppu-/javamaker's idiosyncratic relative URL notation

...which considers an argument containing SEPARATOR characters only as a
relative URL (which it then makes absolute relative to osl_getProcessWorkingDir)
if it starts with a dot (see convertToFileUrl in
codemaker/source/codemaker/global.cxx).  (Which isn't an issue for now, as
convertToFileUrl leaves the relative path unchanged, which is passed to the
unoidl::detail::LegacyProvider ctor in unoidl/source/legacyprovider.cxx and on
to store::FileHandle::initialize in store/source/lockbyte.cxx, which makes a
relative pFilename absolute relative to osl_getProcessWorkingDir.  But it would
become an issue when the given type RDBs are changed to the new UNOIDL binary
format, as the unoidl::detail::UnoidlProvider ctor in
unoidl/source/unoidlprovider.hxx expects an absolute file URL.)
