moveconfig: expand simple expressions

Add support for expanding simple expressions and sizes such as
"(4 * 1024)", "(512 << 10)" or "(SZ_256K)".

This can help to significantly reduce the number of "suspicious"
moves, such as

 'CONFIG_ENV_SIZE="(64 << 10)"' was removed by savedefconfig.

If the expansion fails, it falls back to the original string.
