fix(installer): scan ldd output via REGEX MATCHALL instead of line split

string(REPLACE "\n" ";" ...) treats backslash-n as two literal
characters in CMake's quoted argument syntax, so the per-line splitter
never produced lines and the inner regex never matched. Result: the
transitive-dep walker processed each ldd output as a single 'line' and
copied nothing.

Switch to REGEX MATCHALL across the entire ldd blob, capturing every
'=> /path' pair regardless of line boundaries. Verified locally: the
bundled lib/ now contains libb2/libpcre2/libzstd/libbrotli/libgssapi/
libkrb5 and ldd reports zero unresolved deps.
