package/libcurl: drop override of LD_LIBRARY_PATH

A previous commit [1] (libcurl 7.19.2) configured `LD_LIBRARY_PATH` to
prevent cross-compiling errors when target == host; however, such an
override is no longer needed [2][3] (libcurl 7.37, 7.74) and causes
build errors in some environments. Dropping the override.
