busybox: Make provisions to disable sha256/sha1 accelaration on x86

busybox 1.36 has an ongoing regression on musl/i386 [1] we see same on
glibc systems too.
therefore avoid the affected code by disabling sha256/sha1 sum accelaration
meanwhile

CONFIG_SHA256_HWACCEL and CONFIG_SHA1_HWACCEL are enabled by default
