Remove unused includes of php_random.h (#13131)

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.
