support/testing/tests/fs/test_f2fs: fix test after f2fs-tools bump

In commit
9267b0f14d3d5f4715bad444f44eae47d9d5627c ("package/f2fs-tools: bump to
version 1.15.0"), f2fs-tools was bumped from 1.14.0 to 1.15.0.

It turns out that this version bump causes the output of dump.f2fs to
slightly change.

In version 1.14.0, it looked like this:

Info: Segments per section = 1
Info: Sections per zone = 1
Info: sector size = 512
Info: total sectors = 262144 (128 MB)

In version 1.15.0, it looked like this:

You will notice that the message "Info: total sectors = 262144 (128
MB)" is no longer present, and only "Info: total FS sectors =
262144 (128 MB)" is not present.

Except our test case was precisely looking for this "Info: total
sectors" string in the output, causing the test to fail.

We fix this by simply matching on "Info: total FS sectors" now.
