Fetch from Alpine (musl) and Fedora (glibc)

Arch Linux glibc is too recent for production servers operated by
LmdbJava users. Fedora 41 provides an alternative source for LMDB
0.9.33 with broader glibc compatibility.

Alternatives evaluated for 0.9.33:
* Rocky Linux 9: 0.9.29
* AlmaLinux 9: 0.9.29
* RHEL 9: 0.9.29
* Ubuntu 24.04: 0.9.31
* Ubuntu 22.04: 0.9.24
* Debian stable: 0.9.31
* Arch Linux: 0.9.33 (glibc too recent)
* Fedora 41: 0.9.33 (selected)
