build-sys: support unshare.static 

This patch adds support for building a static version of unshare.
We need to add unshare to the list of possible static programs, and
provide build flags for the compiler and linker, which are equivalent to
the flags of the non-static program, except additional static linking.
See also: commit 2fa60c5 build-sys: support nsenter.static
