bug#26813: [PATCH] re2: add missing '#:modules' imports

[Sergei Trofimovich <slyfox@inbox.ru>]

Noticed as a 're2' build failure:

/gnu/store/...-re2-2017-03-01-guile-builder:1:2276: source expression failed
to match any pattern in form (%modify-phases phases* (delete (quote configure)))

* gnu/packages/regex.scm (re2): add missing '#:modules' imports
