btrfs-progs: build: add --disable-shared and --disable-static

Browse Source 
The build system mentioned in the previous commit builds libraries in
both PIC and non-PIC mode. Shared libraries don't work in PIC mode, so
it expects a --disable-shared configure option, which most open source
libraries using autoconf have. Let's add it, too.
