The post-image.sh script is used in several STM32MP157-based board configs. It had hardcoded device tree file names for the supported boards which were used for matching the expected TF-A binary name. Replace this mechanism with a pair of grep and sed that build the TF-A binary name from the device tree file name. For example, if BR2_TARGET_ARM_TRUSTED_FIRMWARE_ADDITIONAL_VARIABLES contained DTB_FILE_NAME=stm32mp157c-dk2.dtb, the appropriate TF-A file would be named tf-a-stm32mp157c-dk2.stm32. Since the Bash Here Strings are removed with this change, I took the opportunity to remove the only other non-POSIX command, "local", and then I was able to change the shebang to plain /bin/sh, with -eu for simpler error handling.
