[PATCH] t3910: give reason for skipping the test

[Michael J Gruber <git@drmicha.warpmail.net>]

t3910 is skipped for most users because it requires a filesystem which
does automatic conversion between different utf-8 types. Currently, this
results in a skipped test with "no reason given".

Use the skip_all mechanism from our test suite so that a reason for
skipping the test is given to the user.

Alternatively, we could set a prerequisite and mark all tests with that.  Since
it's either or for the whole test skip_all seems more appropriate.  In that
case, we can also flatten the else branch, of course. The current patch is
minimally invasive, though.
