Linux dumper: Properly separate function names from STABS type data.

Browse Source 
STABS strings for N_FUN entries contain a mangled function name,
followed by a colon, followed by type information.  The type
information itself may contain colons; mangled names never contain
colons (they need to be legal assembly-language identifiers).  So the
current code in src/common/linux/dump_symbols.cc:WriteOneFunction that
attempts to separate the mangled name from the STABS junk will
incorrectly include STABS junk in the name, causing demangling to
fail.

Applying the patch below results in changes like these in the symbol
file produced, where an unmangled name followed by STABS junk becomes
a properly demangled name:
