Add build.cwd option

[4513ECHO]

WHAT

(Write what you need)

How about add build.cwd option to change cwd during building?

- name: nkf
  description: Netword Kanji Filter
  url: https://free.nchc.org.tw/osdn//nkf/70406/nkf-2.1.5.tar.gz
  command:
    build:
      cwd: nkf-2.1.5
      steps:
        - make
        - make install prefix=~/.local
    link:
      - from: nkf

WHY

(Write the background of this issue)

Sometimes build.steps requires changing cwd, but cd command is not working.
