Fix selecting clearing and BCE

The commit b78c5085f72 changed the st behaviour enabling BCE capability,
that means erase regions using background color. Problem comes when you
clear a region with a selection, because in this case the real mode of the
Glyph is not the value of term.line[y][x], due in drawregion we had enabled
the ATTR_REVERSE bit.

Removed redundant check in draw code.

We're now clearing empty areas with spaces, so there is no point to check
if character contains non-empty string.
