Make FileManagerDialog::SelectFileImpl() properly accept simple filenames as default path.

Make FileManagerDialog::SelectFileImpl() properly accept simple filenames as default path.

This affects Chrome OS.

1 - If the default path provided isn't managed by the external filesystem
    provider, still keep the base (i.e., file) name.
2 - Fix the JS regex so that it splits the directory/leaf names correctly when
    no path is provided.

BUG=http://code.google.com/p/chromium-os/issues/detail?id=22184
TEST=The main test is that sufficiently-recent Pepper Flash should provide
     correct (Flash) Save As functionality, including the default filename;
     e.g., http://www.everythingflex.com/flex3_fp10/savetodisk/SaveToDisk.html .
     Also, "Save As" for HTML should also provide a default filename on Linux
     chromeos=1 builds.
