esp8266: can't build with MICROPY_PY_USSL = 0 or MICROPY_SSL_AXTLS = 0

[deshipu]

Setting either (or both) of those flags to 0 results in:

moduhashlib depends on the axtls SHA1 crypt, disabling MICROPY_PY_UHASHLIB_SHA1 fixes the compilation. In unix mpconfigport.h we have

#if MICROPY_PY_USSL && MICROPY_SSL_AXTLS
#define MICROPY_PY_UHASHLIB_SHA1    (1)
#endif

Perhaps a similar #if is needed in esp8266/mpconfigport.h

Should I add a patch for this?

Fixed in 056da75. ussl and axtls take about 21k of code space.
