conform tests: call perl with '-I.'

Historically perl includes the current directory in the module search
path. Over the time this has been considered as a security issue and
the recent vulnerabilities [1] made people to reconsider this behaviour.
It is almost sure that this will be removed in the future [2], possibly
for the 5.26 release, although this is not yet firmly decided.

Debian has decided to backport the patches [3], so the perl binary in
unstable do not have '.' in @INC anymore.

This behaviour is used in the conform perl scripts to include the
GlibcConform module. This patch fixes that by calling perl with '-I.'.
This is not a security issue in this case as make ensures that the
current directory is $(srcdir)/conform/ when the scripts are called.
Passing the full path would do exactly the same.
