math/lapack: remove superfluous and broken ranlib invocation

[emaste]

Summary

FreeBSD's base system ar and ranlib have a bug where they exit with
status 0 (success) even in case of fatal errors, which hid the fact that
math/lapacke was invoking ranlib on a non-existent file.  (Presumably the
ranlib invocation was correct when introduced, but broken by some
rework of lapack's upstream build system).

Use of ranlib is unncessary assuming the -s flag is passed to ar (it is
here), so just remove it.

Test Plan

Verify math/lapacke builds and inspect build log to ensure ar contains -s flag

[kevans]

Confirm it builds under poudriere testport then

Approved by: kevans (ports), portmgr (implicit, blanket: build fix)

[jrm]

Ran testport for 11amd64, 12i386, 12amd64, and 13amd64 for math/lapack, math/blas, math/cblas, math/lapacke, and math/xlapack. Everything looks fine.

(Also for posterity, PORTREVISION bump not necessary as the removed command had no effect.)
