app-arch/xz-utils: stop removing *.a files

Upon configure --disable-static, libtool does not create the static
library at all, as long as it is able to create the shared library.
And the *.a file name may be used with shared libraries too (*.dll.a
on Cygwin), so we may end up without any library when removing *.a.

Closes: https://bugs.gentoo.org/687904
Package-Manager: Portage-2.3.66, Repoman-2.3.11
