description:
mk/extract/extract.mk: enclose extract_file in quotes

This prevents unintended shell word expansion.

It also makes that argument visible in "bmake show-all-extract". Before,
it was left out entirely from the output. Now it is printed as an empty
string literal, which at least gives a hint that "there is something".
