package/crun: needs fexecve

Browse Source 
crun unconditionally uses fexecve since its addition in commit
530d6f661e and
ce4dfbb97a:
resulting in the following uclibc build failure:

/tmp/instance-11/output-1/host/opt/ext-toolchain/bin/../lib/gcc/arceb-snps-linux-uclibc/9.2.1/../../../../arceb-snps-linux-uclibc/bin/ld: src/libcrun/crun-cloned_binary.o: in function `ensure_cloned_binary':
cloned_binary.c:(.text+0x1006): undefined reference to `fexecve'

In 6e3f7fbc07 (package/runc: add upstream security fix for
CVE-2019-5736), we made runc unavailable for uclibc toolchains, and crun
uses fexecve for that same reason, to fix CVE-2019-5736.

So, also make crun unavailable for uclibc toolchains.
