Subject: [PATCH] guix import: Fixing detection of Fortran files.

From: Mădălin Ionel Patrașcu<[email-masked]>

This fixes a bug whereby Guix importer considers files like .f.*
being Fortran's files.

(find-files dir "\\.f(90|95)?")

would consider a lot of files with an extension starting with f
being a Fortran file. The right way is to consider only files
ending with .f90 or .f95.

*guix/import/cran.scm: changing pattern of the detection for
Fortran's files to .f(90|95)$.
