linux-firmware: replace mkdir by install

if a setup is using RPM for packaging and there are multiple
recipes that install to ${nonarch_base_libdir}/firmware by using
install -d ${nonarch_base_libdir}/firmware, it will create installation
clashes on image install, as linux-firmware in before this patch
used mkdir -p, which creates different file mode bits (depending
on the current user's settings).

In a particular example
linux-fimware created /lib/firmware with 0600
while other-firmware-package created it with 0644
making the combination not installable by rpm backend

+Subject: [PATCH] Makefile: replace mkdir by install
+
+mkdir -p creates paths that are bound to user's settings and therefore
+can lead to different file mode bits of the base paths accross different
+machines.
+Use install instead, as this tool is not prone to such behavior.
