Travis-CI: change the value of $Config{cc} to clang instead of using …

…PERL_MM_OPT `PERL_MM_OPT` does not work with Makefile.PLs in subdirectories. Running perl Makefile.PL CC=clang; find -name Makefile -exec grep -H '^CC =' {} \; shows that `CC = clang` in the toplevel Makefile, but `CC = cc` elsewhere.
