[PATCH 2/2] binman: nxp_imx8mcst: disable configparser interpolation

[jhaller.oss at gmail.com]

From: Julian Haller <julian.haller at philips.com>

ConfigParser uses %-based interpolation by default, which causes
PKCS#11 URIs containing percent-encoded characters (e.g. %20) to
fail with "invalid interpolation syntax". Disable interpolation
since the CST config format does not use this feature.
