build: bundle-libraries.sh: do not override argv[0] in inner exec calls
Only mangle argv[0] of the first executed process and leave the argument
vector of subsequent invocations as-is to allow child programs to properly
discover resources relative to their binary locations.
Fixes "cc1" discovery when executing the host gcc through the bundled
"ccache" executable.
