build: export _IO_stdin_used symbol in NetworkManager.ver

Browse source 
This symbol is required to decide which version of certain IO functions
to use on various architectures. So we can't strip away the symbol from
the NetworkManager binary as this will lead to segfaults on those
architectures.

/* The _IO_stdin_used symbol is used by the GNU libc to determine
which version of the I/O function should be used. Not
exporting it means that the "old" version is used, causing
crashes or other issues on some architectures. It should be
exported as an anonymous tag, but ld does not support mixing
anonymous version tags with other version tags. Fortunately
the GNU libc is able to cope with the symbol having the wrong
version tag. */
