Fix FORTIFY_SOURCE false positive
When -D_FORTIFY_SOURCE=2 was given during compilation, sprintf and similar functions will check if their first argument is in read-only memory and exit with *** %n in writable segment detected *** otherwise. To check if the memory is read-only, glibc reads frpm the file "/proc/self/maps". If opening this file fails due to too many open files (EMFILE), glibc will now ignore this error.
