strict-aliasing fix for silc-toolkit-1.1-beta2

Hallo.

Here is a trivial fix for strict-aliasing warnings of the latest gcc,
which removes unneeded type-punning of dereferenced pointers.


I: Program is likely to break with new gcc. Try -fno-strict-aliasing.
W: strict-aliasing-punning silcasn1_encode.c: 354, 365
W: strict-aliasing-punning silchttpserver.c: 197

silcasn1_encode.c: In function 'silc_asn1_encoder':
silcasn1_encode.c:354: warning: dereferencing type-punned pointer will break strict-aliasing rules
silcasn1_encode.c:365: warning: dereferencing type-punned pointer will break strict-aliasing rules
silchttpserver.c: In function 'silc_http_server_parse':
silchttpserver.c:197: warning: dereferencing type-punned pointer will break strict-aliasing rules
