Bugs/panics in default alpine linux programs

[arihant2math]

Like #148, but for alpine. All common utilities work, with the exception of networking utilities (they just return "socket(,) not implemented").

• /bin/login: Unhandled syscall 0x67 (setitimer)
• /bin/dmesg: Unhandled syscall 0x74 (syslog)
• /bin/linux32//bin/linux64: Unhandled syscall 0x5c (personality)
• /bin/nice: Unhandled syscall 0x8d (getpriority)
• /bin/watch echo hi:

Every 2.0s: echo hi                                                                                                 1970-01-01 00:03:26
