Find{BLAS,LAPACK}: Cleanup whitespace, style, and comments

Bring whitespace and code style up to date in these scripts.  Both
scripts share the same origin but have diverged over time, so
synchronize them again.  This is relevant because BLAS and LAPACK
detection is often performed simultaneously, so both scripts should
evolve in sync.  While at it, update a few comments.

This update is intended to have no functional changes.

 Find Basic Linear Algebra Subprograms (BLAS) library
 
 This module finds an installed Fortran library that implements the
-BLAS linear-algebra interface (see http://www.netlib.org/blas/).  The
-list of libraries searched for is taken from the ``autoconf`` macro file,
+BLAS linear-algebra interface (see http://www.netlib.org/blas/).

+The approach follows that taken for the ``autoconf`` macro file,
