fix: Fix secubox-profile script syntax and directory path (v0.6.0-r14)

- Changed bash brace expansion `*.{yaml,yml,json}` to POSIX-compliant loops
- Removed `2>/dev/null` from for loop glob (not supported in busybox sh)
- Changed PROFILE_DIR from /etc/secubox/profiles to /usr/share/secubox/profiles
- Fixes "syntax error: unexpected redirection" error
- Fixes listProfiles RPC returning "No response"
