squid: fix configure host contamination

When configuring squid with --enable-esi option,
the following error was observed:
[snip]
checking libxml/parser.h usability... no
checking libxml/parser.h presence... no
checking for libxml/parser.h... no
configure: Failed to find libxml2 header file libxml/parser.h
[snip]
ERROR: This autoconf log indicates errors, it looked at host include
and/or library paths while determining system capabilities.
[snip]

It tried to search libxml header file in host path. Set the SYSROOT
to avoid this host contamination.
