sci-libs/mpfi: add 1.5.4_p20220401

Since the tarball names are different, we can call this a "patch
release" having otherwise the same version components.

The test suite is part of the tarball now, and of course, it fails. I
emailed the authors about this but haven't heard back yet. I think it's
more a case of the test suite being unfinished than of there being real
problems in the code. I've done my best to patch up the (3) failers.

+Subject: [PATCH 2/3] tests/{trec_sqrt.c,rec_sqrt.dat}: fix as many tests as
+ possible
+
+The mpfi_rec_sqrt() function isn't tested at all, because this doesn't
+even compile. First we switch a "I" to a "II" to indicate that it's a
+two-argument function (an in value and an out value). Then, the random
+tests actually pass! But most of the check_data() examples don't, and
+who can say why. I've simply deleted the ones that don't pass? Now "by
+construction," everything passes.

+Subject: [PATCH 3/3] tests: fixup mpfi_div_ext() tests
+
+Again this function was not tested at all, because there was a type
+mismatch in the test file, and if you fixed that then it segfaulted
+because the type_iiii.c implementation was never finished. I've tried
+to hack it together, and to my surprise, it mostly works. The examples
+that don't have been deleted without trying to explain them.
