meson: fix building host binaries with ccache

With CONFIG_CCACHE, $HOSTCC is 'ccache gcc' while $TARGET_CC points to a
single wrapper script. Compiling target binaries with ccache works, but
doesn't for host binaries, because we need to supply an argv array for
argc > 1 in the meson cross file.

Always pass an array for the c and c++ compiler, and while at it, do it
for the target as well - just to be on the safe side if that ever
changes.

Fixes #10982.
