Fix libsanlock build on Unubtu/Debian
    
    LIB_ENTIRE_LDFLAGS included libraries (e.g. -laio -lblkid) instead of
    linker flags. The libraries should be in LIB_ENTIRE_LDDADD and come
    *after* the sources. Otherwisae, the libraries are not linked, and
    loading libsanlock.so fail with undefined symbol error.
