xfrm: xfrm_user: use strscpy() for alg_name
Replace the strcpy() calls that copy the canonical algorithm name into
alg_name with strscpy() to avoid potential overflows and guarantee NULL
termination.
Destination is alg_name in xfrm_algo/xfrm_algo_auth/xfrm_algo_aead
(size CRYPTO_MAX_ALG_NAME).
Tested in QEMU (BusyBox/Alpine rootfs):
- Added ESP AEAD (rfc4106(gcm(aes))) and classic ESP (sha256 + cbc(aes))
- Verified canonical names via ip -d xfrm state
- Checked IPComp negative (unknown algo) and deflate path
