meson: support building libfdt without static library

Browse source 
Some packaging systems like NixOS don't support compiling static
libraries. However libfdt's meson.build uses `both_library()` which
forces the build to always compile shared and static libraries. Removing
`both_library()` will make packaging easier.

libfdt uses `both_libraries()` to support the 'static-build' option.
But we do not need the 'static-build' option as Meson can natively
build static using

> meson setup builddir/ -Dc_link_args='-static' --prefer-static --default-library=static

So drop 'static-build' and then replace `both_libraries()` with
`library()`.
