package/lvm2: disable for musl toolchains

lvm2 doesn't build with musl toolchains due to several assignment of read-only
variable like stdin, stdout and stderr.
Also, it use mallinfo function which is not available with musl.

These issues has been reported upstream [2] but some of them remains
even with the latest stable release 2.02.163.

Fixes:
