scripts/dtc: Call pkg-config POSIXly correct

BugLink: https://bugs.launchpad.net/bugs/1969110
[ Upstream commit a8b309ce9760943486e0585285e0125588a31650 ]

Running with POSIXLY_CORRECT=1 in the environment the scripts/dtc build
fails, because pkg-config doesn't output anything when the flags come
after the arguments.
