package/odhcp6c: needs gcc >= 10

Fixes build errors seen with Gitlab pipeline and this defconfig:
support/config-fragments/autobuild/bootlin-aarch64-glibc-old.config

https://gitlab.com/bkuhls/buildroot/-/jobs/14570080455

aarch64-linux-gcc.br_real: error: unrecognized command line option
 ‘-Wimplicit-fallthrough=5’; did you mean ‘-Wno-fallthrough’?
aarch64-linux-gcc.br_real: error: unrecognized command line option
 ‘-Wshadow=local’; did you mean ‘-Wshadow-ivar’?

Removing all the unrecognized command line options from CMakeLists.txt
showed more build errors during compile:

output/build/odhcp6c-24485bb4b35ab84c17c2e87bd561d026d4c15c00/src/odhcp6c.h:47:46:
 error: expected ‘)’ before ‘__VA_OPT__’
 #define error(fmt, ...) __iflog(LOG_ERR, fmt __VA_OPT__(, ) __VA_ARGS__)

Another pipeline with gcc 9 showed other errors:

/builds/bkuhls/buildroot/br-test-pkg/br-arm-basic/build/odhcp6c-24485bb4b35ab84c17c2e87bd561d026d4c15c00/src/dhcpv6.c:1126:4:
 error: a label can only be part of a statement and a declaration is not a statement
 1126 |    struct dhcpv6_auth *r = (void*)&odata[-DHCPV6_OPT_HDR_SIZE];

so we raise the minimum gcc version to 10.
