[PATCH] ecompress: fix "Argument list too long" for sed (bug 727522)

From: Patrick McLean <[email protected]>

Use sed -f to feed commands to sed via stdin, in order to avoid
the "Argument list too long" error reported in bug 727522.

Fixes: 5508bf7a6db5 ("ecompress: ignore docompress -x files in precompressed QA check (bug 721516)")
