[Buildroot] [git commit] scripts/get-developers: correct type of patches argument

[Thomas Petazzoni]

commit: https://git.buildroot.net/buildroot/commit/?id=1b0df8f23c690d9464d82f4d3e57fe2a334b5d98
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

Current type for 'patches' argument is str. It supposed to only
contain names of files.

If we specify FileType as type, then we don't need to open file ourself
and it allows script to read patch from standard input as well.

e.g.
$ git show -1 | ./support/scripts/get-developers -
