perf tools: /proc/modules names don't always match its name

For instance:
$ grep ^aes_x86 /proc/modules
aes_x86_64 9056 2 - Live 0xffffffffa0091000
$ l /lib/modules/2.6.31-tip/kernel/arch/x86/crypto/aes-x86_64.ko
-rw-r--r-- 1 root root 136438 2009-09-22 19:05 /lib/modules/2.6.31-tip/kernel/arch/x86/crypto/aes-x86_64.ko
Handle that by introducing a strxfrchar routine that replaces
dashes with underscores when matching file names to loaded modules.
