parse-duration tests: Fix test failure on mingw

[Bruno Haible]

On mingw 10, I see this test failure:

FAIL: test-parse-duration.sh
============================

../../gltests/test-parse-duration.sh: line 64: test: 38898367
: integer expression expected
test-parse-duration fatal error:  38898367
 is not 38898367
FAIL test-parse-duration.sh (exit status: 1)

The cause is that there's a CR at the end of the tested output.

This patch fixes it.

        parse-duration tests: Fix test failure on mingw.
        * tests/test-parse-duration.sh: Transform CRLF to LF in the output,
        before analyzing the output.
