build: avoid build failure on systems that must compile regexec.c
With --enable-gcc-warnings, compiling regexec.h would fail due to
its use of a single variable-length array.
* configure.ac: Add -Wvla to the list of disabled warnings and
remove most of the others, that no longer need to be disabled.
