package/pkg-utils.mk: rationalise kconfig option mangling
Currently, we have three macros that may mangle a .config file. All three are modeled after the same pattern: removing the existing option from the .config file, then adding the new definition for that option; all three also implement that pattern with the same commands: sed and echo. This is all good so far, because it was simple enough, and they always worked on a file passed in parameter. However, we're soon going to change this file parameter to make it optional, so that the file will then be auto-deduced for the current package. In that case, the file to sed and echo into will be a more complex structure than just the parameter. As such, move the actual mangling down to a helper macro, that is called from the three existing ones. Signed-off-by: Yann E.
