uClibc++: Remove faulty patch

uClibc++: Remove faulty patch

This patch was originally added to fix compilation with v4l2rtspserver.
Turns out it was v4l2rtspserver that was broken, not uClibc++. This now
causes issues with a different package where the arguments are being
split.

Note that with this patch, shellcheck throws an error:

SC2068: Double quote array expansions to avoid re-splitting elements.
