popen: don't use exec-on-close flag, which is non-POSIX

The "e" flag was an extension on atleast OpenBSD:
"If the letter "e" is present in the string then the close-on-exec flag shall
 be set on the file descriptor underlying the FILE that is returned."

POSIX says:
https://pubs.opengroup.org/onlinepubs/9699919799/functions/popen.html

"If mode is any other value, the result is unspecified."

This causes atleast on HaikuOS to fail and set errno EINVAL.

Theres no need for this flag too so remove it.
