libgcrypt module: remove disable-asm

Idea is to be able to generate keys in memory and take advantage of cpu extensions where available.

By disabling --disable-asm in libgcrypt 1.10.1:

config.status: executing gcrypt-conf commands

        Libgcrypt v1.10.1 has been configured as follows:

        Platform:                  GNU/Linux (x86_64-pc-linux-musl)
        Hardware detection module: libgcrypt_la-hwf-x86
        Enabled cipher algorithms: arcfour blowfish cast5 des aes twofish
                                   serpent rfc2268 seed camellia idea salsa20
                                   gost28147 chacha20 sm4
        Enabled digest algorithms: crc gostr3411-94 md4 md5 rmd160 sha1
                                   sha256 sha512 sha3 tiger whirlpool stribog
                                   blake2 sm3
        Enabled kdf algorithms:    s2k pkdf2 scrypt
        Enabled pubkey algorithms: dsa elgamal rsa ecc
        Random number generator:   default
        Try using jitter entropy:  yes
        Using linux capabilities:  no
        FIPS module version:
        Try using Padlock crypto:  yes
        Try using AES-NI crypto:   yes
        Try using Intel SHAEXT:    yes
        Try using Intel PCLMUL:    yes
        Try using Intel SSE4.1:    yes
        Try using DRNG (RDRAND):   yes
        Try using Intel AVX:       yes
        Try using Intel AVX2:      yes
        Try using ARM NEON:        n/a
        Try using ARMv8 crypto:    n/a
        Try using PPC crypto:      n/a

    To support PPC crypto, it seems we will need yasm.
    To support linux capabilities, libcap would be required as well later on. :/ another point for rng-tools (which also depends on libcap-ng)

As on master otherwise with --disable-asm:
