tests/locale.sh: fix test that depended on 'od' whitespace output

Different implementations of the 'od' command may legitimately vary
the whitespace they output between fields. One of the regression
tests checked 'od' output without tolerating whitespace varieties,
which is not portable. For example, the BSD 'od' implementation
outputs more whitespace than the variant used to write the test.

src/cmd/ksh93/tests/locale.sh:
- In test "incorrect string from printf %q", use 'awk' to eliminate
  whitespace from 'od' output before checking results.

(cherry picked from commit 7aa830bd3a2284f7228ee7189f5671749c3f2682)
