[PATCH 1/9] scripts: kconfig: merge_config.sh: use POSIX '=' in test

[Vincent Mailhol (Arm)]

merge_config.sh yields this warning:

  ./scripts/kconfig/merge_config.sh: 384: [: false: unexpected operator

This happens because the script runs under /bin/sh but compares
strings using the '==' operator, which is a bash extension. The POSIX
test command only specifies '=' for string equality.

Replace '==' with the POSIX-compatible '=' so the script works when
run with /bin/sh as intended.

Fixes: dfc97e1c5da5 ("scripts: kconfig: merge_config.sh: use awk in checks too")
