biology/htslib: fix build on armv7 (again)

The patches provided by me in 2023 to fix the build on armv7 were
upstreamed shortly after. In a subsequent update to the port, it
appears that the maintainer had then reversed these patches (?!),
effectively undoing my now upstreamed bug fix.

Remove the bogus patches to fix the build.
