libselinux: fix required alignment for sha1.c on mac
When building on mac with ANDROID_HOST=y, clang complains:
sha1.c:73:33: error: cast from 'uint8_t *' (aka 'unsigned char *') to 'CHAR64LONG16 *' increases required alignment from 1 to 4 [-Werror,-Wcast-align]
CHAR64LONG16* block = (CHAR64LONG16*) workspace;
Rather then casting the bytearray to the CHAR64LONG16 union,
just create a stack workspace of type CHAR64LONG16.
This will prevent alignment issues with the data accesses.
