tpm: select ANON_INODES for proxy driver

The newly added vtpmx driver fails to build if CONFIG_ANON_INODES
is disabled:

drivers/char/built-in.o: In function `vtpmx_fops_ioctl':
(.text+0x97f8): undefined reference to `anon_inode_getfile'

This adds a Kconfig 'select' statement to ensure it's always there
when we need it.
