Dear Guix,

By updating samtools to 1.11, I introduced a build failure for
bedtools. More precisely, the tests for intersect break in precisely
this way:
https://github.com/arq5x/bedtools2/issues/814

With the following patches, I'd like to add samtools-1.9, htslib-1.9
(samtools depends on that) to fix this problem with bedtools.

Alternatively we could add a patch to disable the failing bedtools
tests.  I manually inspected the test results, and seem to match
perfectly (indicating that there's no problem with bedtools).

Kind regards,
Roel Janssen
