    tools/e2fsprogs: fixup STAGING_DIR_HOST path evaluation in shell scripts
    
    We have to use curly braces on the exported STAGING_DIR_HOST env variable,
    instead of evaluating it directly as we are not in Make but a separate
    shell script.
    
    Otherwise it would fail with:
    staging_dir/host/bin/compile_et: line 6: STAGING_DIR_HOST: command not found
    staging_dir/host/bin/mk_cmds: line 5: STAGING_DIR_HOST: command not found
    
    And so when krb5 tries to build it will fail as compile_et and mk_cmds will
    return an error.
