lockdev: fix build with the musl C library
When the musl C library is used, the __GNU_LIBRARY__ symbol is not
defined, so the lockdev code doesn't know what to do. To work around
this, we explicitly pass __GNU_LIBRARY__ when building with musl, this
musl provides what's needed for lockdev to build, as if we were
building against glibc.
Fixes:
