tools: bzip2: use static lib and tools

Currently, bzip2 is built with a dynamically linked library on which all
of the bzip2 tools depend on.

However, when trying to use the staging dir bzip2 during building on
Fedora 40 the following error appers:
staging_dir/host/bin/bzip2: error while loading shared libraries: libbz2.so.1.0: cannot open shared object file: No such file or directory

Looking into it, the binary is dynamically linked:
$ ldd staging_dir/host/bin/bzip2
linux-vdso.so.1 (0x00007f5ebd9ff000)
libbz2.so.1.0 => not found
libc.so.6 => /lib64/libc.so.6 (0x00007f5ebd7f5000)
/lib64/ld-linux-x86-64.so.2 (0x00007f5ebda01000)

libbz2.so.1.0 is installed into staging_dir/lib but that directory is not
evaluated for the required libraries and Fedora only ships:
/usr/lib64/libbz2.so.1
/usr/lib64/libbz2.so.1.0.8

Thus it cannot find the libbz2 that bzip2 is linked against and thus
trying to use bzip2 will fail and stop compilation as it is used for
bzip2 compressed tarballs.

So, to avoid OpenWrt compiled bzip2 to even attempt to load a required
library from the host we can just static compile libbz2 and bzip2.
