Subject: [PATCH] kernel-install: avoid process substitution

bash implements process substitution using /dev/fd/N (this is documented

in man bash). We'd like kernel-install to work in chrooted RPM

scriptlets without /dev.

We can use here-strings instead. bash uses temporary files to implement

those.

(cherry picked from commit db1e2bfc4f049261ae2d407568ff39569b36d98c)
