xfsprogs: fix build with libunistring

The latest xfsprogs bump to version 4.15.1 added an optional dependency
on libunistring. Make sure we build libunistring before xfsprogs.

xfsprogs also added -lunistring to its make dependency. This does not
work very well with cross compilation because make does not know about
sysroot. Add a patch to remove this dependency.

To make shared only link with libunistring work, we also need to extend
the -static-libtool-libs patch to cover xfs_scrub as well.

+
+Commit 4bbed4ecc2a (xfs_scrub: warn about normalized Unicode name collisions)
+added -lunistring to the list of the xfs_scrub dependencies. When cross
+compiling make fails to find the library on the target sysroot:
+
+make[3]: *** No rule to make target `-lunistring', needed by `xfs_scrub'.  Stop.
+
+Remove -lunistring from make dependencies of xfs_scrub to fix that.
