[Buildroot] [git commit] package/libxmlrpc: add BR2_USE_MMU dependency

[Julien Olivain]

commit: https://git.buildroot.net/buildroot/commit/?id=059138326eb1e411dfcedc7947263e95a74efd4b
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

Build fails with:
server.c: In function 'ServerDaemonize':
server.c:1590:13: error: implicit declaration of function 'fork'
[-Wimplicit-function-declaration]
 1590 |     switch (fork()) {
      |             ^~~~

Hence, add BR2_USE_MMU to avoid building with toolchains without MMU
support.

Fixes:
