tdf#129430 PPTX export: fix workaround for "At least" line spacing

to avoid bad overlapping lines.

PPTX does not have the option "At least", so line spacing
with this setting is converted to fixed line spacing.
Improve this workaround to use single line spacing, if the
"At least" value is lower than the size of the characters,
like "At least" is handled by Impress.
