Before this change php_random.h was listed in 146 different *.dep files for a
env CC=clang ./configure --without-sqlite3 --without-pdo-sqlite
build, after this change it's only listed in 110 of them, preventing uselessly
recompiling those files when working on ext/random, mostly caused by the include
in ext/standard/basic_functions.h.
