rpm-sequoia: add ptest

In rpm-sequoia, some default paths in test code (OUT_DIR,
CARGO_MANIFEST_DIR) are invalid at runtime and cause test failures.

To fix this, patch the test code (symbols.rs) to support overriding these
paths via optional environment variables: FORCE_RUNTIME_PATH_LIB and
FORCE_RUNTIME_PATH_SRC.

Also make -ptest package RDEPEND on -dev package.

Tests take less than a second so this is added to PTEST_FAST.
