build: add QMAKE_RPATHDIR for the sysroot cross-build

Browse Source 
Building against a local sysroot rather than an installed
libnymea-sunspec-dev left the resulting binaries unable to find
libnymea-sunspec1 at run time: the sysroot is not in the dynamic
linker's cache, so -L alone is not enough and every test had to be
launched through LD_LIBRARY_PATH.

Only the NYMEA_SUNSPEC_PATH branch is touched. The package build resolves
the library through pkg-config and gets no rpath, as before.

Verified both ways: with NYMEA_SUNSPEC_PATH the binary carries a RUNPATH
to the sysroot, resolves libnymea-sunspec1 there and runs its 44 tests
with LD_LIBRARY_PATH unset; without it, no sunspec rpath is generated at
all.
