This was found by AI sandbox build when doing other fixes
to EAL. The sxe2 driver was doing handrolled meson to pick
up AVX which fails if security library not present.
Fix build failure when building with
"meson setup build -Denable_libs=eal":
drivers/net/sxe2/meson.build:37:24: ERROR:
Unknown variable name "static_rte_security".
Use sources_avx2 and sources_avx512 instead of hand-rolled
static libraries.
Fixes: 59d866861188 ("net/sxe2: add AVX2 Rx and Tx")
Fixes: 0af0bdcdcf83 ("net/sxe2: add AVX512 Rx and Tx")
