[Buildroot] [git commit branch/2022.11.x] package/rtl8192eu: fix build failure on Big Endian architectures

commit: https://git.buildroot.net/buildroot/commit/?id=d878588b532014da392c19030dd03cb804ce8739
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/2022.11.x

Let's disable the CONFIG_PLATFORM_I386_PC that is set to y by default
involving the endianness to be set to little. This way we can set the
CFLAGS according to architecture with some default define like:
-DCONFIG_IOCTL_CFG80211
-DRTW_USE_CFG80211_STA_EVENT
-Wno-error
