[PATCH 1/3] build: avoid the export of NETCACHE variable

[Víctor Manuel Jáquez Leal <vjaquez igalia com>]

NETCACHE variables is not used for compiler tasks, so the PKG_CHECK_MODULES
can be replaced by a PKG_CHECK_EXISTS, which does not export an automake
variable, as we only need to know if cache operations are supported in libsoup
given the version number.
