crypto/aes/asm/asm-sha{1,256}-armv8.pl: add missing function alignment

clang-22 reported missing alignment on MacOS:

    ld: warning: arm64 function not 4-byte aligned: _asm_sha1_hmac_aescbc_dec from libcrypto.a(libcrypto-lib-aes-sha1-armv8.o)
    ld: warning: arm64 function not 4-byte aligned: _asm_sha256_hmac_aescbc_dec from libcrypto.a(libcrypto-lib-aes-sha256-armv8.o)

Add ".align 4" directives to the affected functions.
