[Buildroot] [PATCH v2 2/2] i2c-tools: install library and header to staging

[Brad Love]

When the dynamic/static library of i2c-tools is enabled it is installed
to the target destination. However, in order for external packages to
link against it, it must also be installed to staging.

Here, the flag is set to install the package to staging. The
INSTALL_STAGING command is included to complete the operation.
