  Fix tr/// determination of inplace editing for EBCDIC

I realized as a result of fixing GH #17654, that the code didn't
properly decide if a tr/// can be done in-place on EBCDIC platforms.
Since we didn't have an EBCDIC smoker at the time, I couldn't be sure
that the fix actually worked.  Now that we do have a smoker, I have
successfully tested it.

This patch is constructed so that the code generated on non-EBCDIC
platforms should not be changed by it.

  t/re/regexp.t: Fix to properly handle EBCDIC

5.31 commit 2b7f9bbf39f71c0d94db058b0110977a9470c1b2 caused this to not
work at all on EBCDIC platforms.

There is a bug in Configure where it doesn't handle 'none' properly for
platforms which have no flag to indicate don't optimize.  Instead of
fixing this for 5.32 at this late date, change the hints file for os390
to use the equivalent " ", that does work.

  t/TEST: Skip some cpan module testing on EBCDIC

These modules have known problems, varying from one test failing, to not
working at all.  This is a big improvement from earlier releases where
all of cpan testing was entirely ckipped.

  Log Message:
  -----------
  pod/perluniprops: Split run-on lines before '\'

This changes mktables, which generates this pod, to consider long pod
lines to be splittable before most backslashes.  On os390, the lack of
this caused a line to not be split at all, creating a Porting test
failure.

There is also a current rule that you can split at a lowercase/uppercase
boundary.  This works for the limited domain this code is run on.  But
it shouldn't split \cK.  So don't do the split if the lowercase is a
single letter preceded by a backslash.

  op/exec.t: ENOTDIR is a legit errno

This test file does a system() on a non-existent file, and checks
that an error happens, and that the errno is one that is expected.
Prior to this commit it didn't think that ENOTDIR could happen.

But it can If PATH contains a component that is plain file, or, on some
systems, a component simply doesn't exist.

I examined the possible errnos listed in a Linux man page for this, and
this looked to be the only one that is likely to come up that weren't
already covered.

This fixes GH #17515
