fix: type roots behavior is inconsistent with tsc

[PeachScript]

修复解析 typeRoots 的默认行为与 tsc 不一致的问题。

问题触发的情形：在 monorepo 使用根目录 tsconfig.json 的情况下，tsc 的 typeRoots 默认从根目录开始解析，仅包含根目录的 node_modules/@types，但 father 由于没有指定 configFilePath 则会从 cwd 开始解析，将会包含子包的 node_modules/@types，与 tsc 的差异行为会导致某些 IDE 不报错的情形但 father d.ts 生成报错，详细 case 可参考下方 issue。
