From: Daniel Gomez <da.gomez@samsung.com>

The script uses #!/bin/sh but == for string comparison, which is a bash
extension. This causes an error on systems where /bin/sh is not bash:

    ./scripts/kconfig/merge_config.sh: 380: [: false: unexpected operator

Use = instead, as used in the rest of the script.

Fixes: dfc97e1c5da5b ("scripts: kconfig: merge_config.sh: use awk in checks too")
