nss: Fix SHA_HTONL bug for arm 32be.

Rpm use nss as digest crypto library and which will cause an error as follows:

error: test-manual-1.2.3-20181012.noarch.rpm: Header SHA1 digest: BAD (Expected
f1deb7dc4a10742d88ccd1e967dbc62ae45095a5 !=4ad9d7dad6d70d6086eefec62612ad5d77f2fe81)  => this value is wrong
error: test-manual-1.2.3-20181012.noarch.rpm: not an rpm package (or package manifest)

The error is caused by SHA_HTONL in nss, for there is no need to reverse the host value for arm 32be, so fix it.
