sqlite3: fix arm endian issue

Forum user portuquesa raised a topic (see [1]) about being unable to use
Asterisk on his armeb xscale device. We narrowed it down to sqlite3.
Asterisk was unable to insert a simple table into its db.

In short, sqlite3 assumes little endian for every ARM device. This
worked OK for 4 Byte bit (unaligned) access. But once upstream (back in
2015) added a function which accesses 2 Bytes (see [2]) this failed for
some (if not all) ARM big endian devices. ARM CPUs are bi-endian for 4
Byte reads but not for 2 Byte reads.

This patch fixes the problem by setting the endianness adequately for
ARM targets, for both 32 bit and 64 bit varieties. The patch was applied
upstream (see [3]).
