kconfig: Don't leak 'option' arguments during parsing
The following strings would leak before this change:
- option env="LEAKED"
- option defconfig_list="LEAKED"
These come in the form of T_WORD tokens and are always allocated on the
heap in zconf.l. Free them.
Summary from Valgrind on 'menuconfig' (ARCH=x86) before the fix:
LEAK SUMMARY:
definitely lost: 344,616 bytes in 14,355 blocks
...
Summary after the fix:
LEAK SUMMARY:
definitely lost: 344,568 bytes in 14,352 blocks
