add guard in Formula#file_modified? to prevent git popup
add guard in Superenv.bin before calling MacOS::Xcode.version
add guard against missing Xcode/CLT in Xcode.uncached_version
return nil instread of 0 in uncached_version when Xcode/CLT are not present, to distinguish from linuxbrew behavior
checks against pour_bottle? and needs_relocation?, add guard around keg.relocate_install_names to check pour_bottle?/needs_relocation? as well
needs_relocation? becomes skip_relocation?, use cellar attr to indicate relocation instead of does_not_need_relocation
MacOS.can_build? becomes MacOS.has_apple_developer_tools?
There are times (e.g. `ocaml`) when the `text_executable?` test will
match even although `file` does not consider it a text file. Ensure
that it's relocated in this case correctly.

Work out what's text and what's not using `file`. Also, rename
`keg_fix_install_names` to `keg_relocate` because that's a more
accurate description of what it does now.
