crypto: tcrypt - remove mode=1000

Browse Source 
The lists of algothms checked for existence by
    modprobe tcrypt mode=1000
generates three bogus errors:
    modprobe tcrypt mode=1000

    console log:
    tcrypt: alg rot13 not found
    tcrypt: alg cts not found
    tcrypt: alg arc4 not found

rot13 is not an algorithm in the crypto API or tested.

cts is a wrapper, not a base algorithm.

arc4 is named ecb(arc4), not arc4.

Also, the list is missing numerous algorithms that are tested by
other test modes:
    blake2b-512
    blake2s-256
    crct10dif
    xxhash64
    ghash
    cast5
    sm4
    ansi_prng

Several of the algorithms are only available if
CONFIG_CRYPTO_USER_API_ENABLE_OBSOLETE is enabled:
    arc4
    khazad
    seed
    tea, xtea, xeta

Rather that fix that list, remove test mode=1000 entirely.
It seems to have limited utility, and a web search shows no
discussion of anybody using it.
