xfe: update to 1.44

[mtboehlke]

Also patch to ignore missing po file during check

General

• This is a new package and it conforms to the quality requirements

Have the results of the proposed changes been tested?

• I use the packages affected by the proposed changes on a regular basis and confirm this PR works for me
• I generally don't use the affected packages but briefly tested this PR

I don't generally use this file manager, but I do sometimes put it on portable media installs to avoid installing a larger toolkit like gtk. I can confirm that the new version runs and appears to behave as expected.

In case anyone does wonder, I changed the short description to be little more descriptive and so xlint doesn't complain.
