This changes the prefixes of the symbols generated from USEMODULE and
USEPKG variables. The changes are as follow:
KCONFIG_MODULE_ => KCONFIG_USEMODULE_
KCONFIG_PKG_ => KCONFIG_USEPKG_
MODULE_ => USEMODULE_
PKG_ => USEPKG_
Introduced 'GNRC_PKTDUMP_MSG_QUEUE_SIZE_EXP' to hold exponent
value and made GNRC_PKTDUMP_MSG_QUEUE_SIZE dependant on
GNRC_PKTDUMP_MSG_QUEUE_SIZE_EXP.
Moved 'GNRC_PKTDUMP_MSG_QUEUE_SIZE_EXP' to 'CONFIG_' namespace.
