Fix two issues that caused libcxx source path not to be inferred
correctly when not specified explicitly:
1. get_lit_conf() uses default value only if the lit variable is set
to None. Due to the mehod of substituting lit.site.cfg, they were
"" rather than None when unset, effectively causing the default never
to apply. Instead, use 'or' construct to use the default whenever
get_lit_conf() returns a false value.
2. If os.path.join() is given a component starting with '/', it takes
it to be an absolute path and ignores everything preceding it.
Remove the slash to correctly append subdirectory.
With these two fixes, libunwind tests start working on NetBSD buildbot
again.
