[PATCH] configure.ac: Add support for zstd-compressed charmaps

[Thomas Staudinger]

Solus, like apparently OpenMandriva and potentially other Linux distros, carries a glibc patch to compress charmaps with zstd instead of gzip. While neat this leads to a build failure for m17n-db. This patch adds support for .zst charmap files to configure.ac by expanding the logic already used for .gz charmaps
